Update 10/8 | Day 19 | Week 2

Friyay!
Looks like the plants slowly settling down and catching up on veg growth.
Special thanks to @Rexer and @FelipeBlu for guiding and helping me out a lot lately Ps. Hydrogen Peroxide definitely had some positive impact.

Getting close to hit three weeks mark and things will get more interesting in a week or two
Hopefully DWC Critical recovers fast from excess Fe(iron) which has most likely caused lockouts and major Calcium and other deficiences…
Hydroguard also arrived today 10/8, so things should get better soon.

Then let’s take a look at the comparison.
Tent temp: 21-25C night/day
Res temp: 21C
Humidity: 38% RH
Light schedule: 20/4 (18/6 once flowering starts)
- Coco feed twice per day ~0.35l/plant
- Coco pH: 6 EC: 1.4

Blackberry Kush (soil)
She didn’t flinch much after I topped her. Her internode spacing is very dense. Will start LST:ing today.
Feed: ~0.2l/24h (M: 0.85ml/l, G: 1.4ml/l & B: 0.6ml/l) plus additional seaweed/Kelp extract

VS.

Blackberry Kush (coco)
Shes still being very tiny.
Feed: M: 1ml/l, G: 1.1ml/l, B: 0.6ml/l & Cal/Mag: 0.8ml/l

Lol shes having a retarded baby leaves. One three finger and other one has 5. Serrated leaves also having like thumbs..

Critical 2.0 XL (coco)
Lanky ass stick. She will get bushier as soon as the new shoots starts to develop. …Hopefully
Feed is same as above, but 1.2ml/l Cal/Mag. Showing just a sliiight burn on tips. At that stage 1.4 EC seems to be max for her.

VS.

Critical 2.0 XL (DWC)
Flushed the basket yesterday with 3% Hydrogen Peroxide incase there was any gunk, pests or larves inside the medium.
Nuclear clear and one tsp into the res for a little extra oxygen and for sterilization. Fortunately Hydroguard arrived today so BT Bacillus can take care of the water and roots.

Made a res change again since there was way too much, almost 14ppm Fe… Hopefully thats the reason for Ca lockout/deficiency.
New res mix:
- 1.3ml/l Cal/Mag (100ppm Ca & 68ppm Mg)
- 1ml/l Micro
- 2ml/l Grow
- 0.9ml/l Bloom
The new mix should have a nice K bump (~162ppm) what the plant really needs right now.
EC: 1.7 (overnight climbed to 1.8 and the plant drank almost like 0.5l, so should maybe slightly lower the EC)
pH: after mix up nutes buffered it down to 6.4 and lowered it to 5.9 (trying to keep it between 5.9-6.3 couple of days for the best Ca absorption)
Res temp stays between 21-21.5C

Before the res change & peroxide flush:

Less than 12hrs later:

Also a quick look at the clone cabinet.
NL#1 and NL#3 (in 1L Air Pots) already at late ripenin stage. Might harvest them in a 7-10 days.
NL#2 in 4L Air Pots need two or couple more weeks.

Have a nice and cloudy weekend!

 

[FelipeBlu]

EC: 1.7 (overnight climbed to 1.8 and the plant drank almost like 0.5l, so should maybe slightly lower the EC)

Heya V,
I don’t do DWC, but if the plant is drinking more than eating and the EC increases as a result, I believe the action is to add water to top up and bring the EC back to initial.

Heya V,

Heya. Yup topped with tap water + Hydroguard mix, as it finally arrived.
EC back to 1.7 and pH adjusted to 5.9

If it keeps raising back to 1.8 I guess then gotta go ”low” as 1.5-1.6mS/cm

 

[Verbalist]

Quick update 10/9

Blackberry Kush automatic on soil showed the first pistils today! Thats early, 20 days only. She will most likely start to stretch now.

Today did a first LST exercises BB Kush will be easier to tie when the new shoots gets longer.

Also you may have seen this mini bag seed OG Kush (wish it had been a male so that I could pollinate OG Kush x Northern Lights = Lights out)
Anyway shes like 13-15cm (~5inches) tall and Ive been LST:ing her so the stem is like a spiral or S-letter. Shes planted in 0.25L (8oz) mini pot.
Hopefully results are couple grams of spicy OG Kush

Have a nice saturday!

Update 10/14 | Day #25 | Week 3

Helllow! And sorry no update in a while. Been super busy and yday had to go for a trial.. gotta hope they drop the charges

Plants have taken big spurts in past five days. Still haven’t figured out which is causing this Ca def or lockout for BOTH Criticals (coco and dwc) and BB Kush on soil..
Ive literally tried almost everything and fixed/adjusted many factors.

10/14 - Day 25
- - -
Tent temp: 22-23C
Humidity: 45-55%
VPD: 1.16kPa (should be perfect for veg)
~ Extra CO2 Bag added to hang if correct VPD helps for transpiration and CO2 usage
~ TS 1000 (150W) dimmed down to 50% and 15" (~40cm) above canopy.

Blackberry Kush (soil)
She showed her first pistils 5 or 6 days ago. And since that shes been stretching mad.
Slight N excess/tox visible on this plant. Also there was some light stress when newest growth leave tips started to turn yellow and plant got droopy like 1-2h before lights went off.
Yday flushed this one to get rid off excess N. And cutting down the N feed as soon as the stretch looks to be over.
Feed:
- 0.66ml/l CalMag agent
- 0.75ml/l GHE Micro
- 1.4ml/l GHE Grow
- 0.9ml/l GHE Bloom | EC: 1.4 and pH adjusted to 6.5 before irrigation

Blackberry Kush (coco)
She definitely got too stunted by the root damage to grow properly
Shes also showed first pistils already.. If she actually starts to flower that small I may just ditch it and make room for a new strain. So strain suggestions are listened, if you would like to see some autoflowers to grow!

Critical 2.0 XL (coco)
There has been some problems with Ca&Mg uptake with this one as well. And excess Nitrogen visible at the newest growth (clawing)
Flushed her also to get rid of excess N. Thought a good flush could balance the nutrient uptake. No visible difference at least yet.
Feed (0.7l/24h):
- 150ppm of Canna Cal/Mag
- 0.35ml Hydroguard
- 0.3ml/l GHE Micro
- 1.3ml/l GHE Grow
- 0.5ml/l GHE Bloom
EC: ~1.1
pH: 6

Most likely topping her today.

Critical 2.0 XL (DWC)
Pretty much tried to give perfect environments for her. Growth has been fast, but new shoots being thin and weak.
Did a res change yesterday:
- Tap water starting EC 0.15-0.2
- Canna CalMag until I get 0.4-0.5 EC (200-250ppm)
- 0.5ml/l Hydroguard
- GHE Grow: 0.9ml/l (EC check: 0.8)
- GHE Micro: 0.5ml/l
- GHE Bloom: 0.5ml/l (EC: 1.2)
- pH buffered down to 5.8 & ending EC 1.3
- Reservoir temp: 20C
During the night water level had dropped notably and EC were 1.1 (she were so hungry for something) but looks like should rise up EC to 1.4 or 1.5
Ive tried all they way up to 1.9 EC almost a week ago, but felt like she only drank so tried this res with lower EC.

See how weak the stems are at the tip of the longest nodes. The tips are almost falling over when they lean like that.

All the feedback is welcome
Thanks for stoppin by, V.

Nitrogen excess/toxicity
GHE nutes being actually very strong. Fed them couple of days with recommended dose ~1.6EC / 750-800ppm and N was first one showing signs of excess

So decided to buy a Canna’s Flush for it and good to have for the future. Also bought Canna CalMag agent because couldn’t no longer contrive anything else than try another product.
Canna CaMg agent contains nice 3:1 ratio Ca&Mg, but the downside is theres 6% total N included… online stock gave their word that Canna’s CalMag agent would contain Fulvic and hummus acids plus Silicates but none of these mentioned on bottle labels.

Idk if this gets even more tricky now when combining calmag agent and micro. Summoning brother @FelipeBlu even tho hes on the road, but wanted to state and share one more thing regarding GHE aka Tera Aquatica’s Micro; bottle has 6% Fe Chelated. There is shit loads of iron in it. And as it is in chelated form (means iron is more easily available for the plant roots) I started to wonder as those Fe ions are bound together to make them chelated form, could they somehow block Ca and/or Mg uptake?
Since every plant has more or less Ca deficiency looking symptoms, it has to be nutrient or tap water related issue.
Any thoughts @West Hippie @Rexer what I could have missed? Ive flushed the netcup multiple times now, Hydroguards Bacillus bacteria should be active and taking care of the roots, and Ive tried from 50 up to 150ppm range of Ca, and from 20 to 70ppm of Mg (if less could have been more….)

Doesn’t this look like a late stage Ca deficiency?

Weird thing is it appears on oldest leaves first and moves upwards at the same rate as former wither

Roots are looking good and nothing on yellow sticky straps…
Drives me crazy

 

[FelipeBlu]

Considering the size of the affected leaves, the fact that they are lower to mid, and it is not affecting upper, newest growth, I would have to guess that it’s probably K and Mg def instead of Ca.

At this point, I have no idea if the plant can recover from Fe toxicity - sorry - it just isn’t anything I have ever encountered before. And since Mulder’s chart doesn’t indicate an antagonistic relationship between Fe, K, and Mg, I’m not sure what is going on.

 

[Rexer]

Hey Verbalist, I'm no good at running the numbers like Felipe, but I'm just going to ask a few things to help stew it over....

Nitrogen excess/toxicity
GHE nutes being actually very strong. Fed them couple of days with recommended dose ~1.6EC / 750-800ppm and N was first one showing signs of excess

So decided to buy a Canna’s Flush for it and good to have for the future.

I'm not sure what exactly Canna Flush is, but I don't think it would be something needed. Flushing is a whole topic on itself, and personally if you need to rinse salts from roots, RO water with a touch of cal mag ph'd to 5.8 will do it. No special products needed (unless there's something I don't get about those flushing products).

Feel free to ask members here before buying products, we have no stake in if you buy or don't, so you'll get honest info on if its needed. That being said, it's your money and you never know it might be helpful.

Also bought Canna CalMag agent because couldn’t no longer contrive anything else than try another product.
Canna CaMg agent contains nice 3:1 ratio Ca&Mg, but the downside is theres 6% total N included… online stock gave their word that Canna’s CalMag agent would contain Fulvic and hummus acids plus Silicates but none of these mentioned on bottle labels.

So...what's the NPK number on that? Most look for a CalMag supplement that is low on nitrogen, as that high nitrogen can be problematic in flower.

Idk if this gets even more tricky now when combining calmag agent and micro. Summoning brother @FelipeBlu even tho hes on the road, but wanted to state and share one more thing regarding GHE aka Tera Aquatica’s Micro; bottle has 6% Fe Chelated. There is shit loads of iron in it. And as it is in chelated form (means iron is more easily available for the plant roots) I started to wonder as those Fe ions are bound together to make them chelated form, could they somehow block Ca and/or Mg uptake?

above my head sorry. I'd rather say I don't know then give wrong advice.

Ive tried from 50 up to 150ppm range of Ca, and from 20 to 70ppm of Mg (if less could have been more….)

how long in between these adjustments did you wait? I'm talking any changes since you last posted....

Roots are looking good and nothing on yellow sticky straps…
Drives me crazy

Finally some good news!!

 

[Verbalist]

Considering the size of the affected leaves, the fact that they are lower to mid, and it is not affecting upper, newest growth, I would have to guess that it’s probably K and Mg def instead of Ca.

At this point, I have no idea if the plant can recover from Fe toxicity - sorry - it just isn’t anything I have ever encountered before. And since Mulder’s chart doesn’t indicate an antagonistic relationship between Fe, K, and Mg, I’m not sure what is going on.

Yup damaged leaves are damaged and wont recover. But as one leave dies it jumps up to the next one.

It feels and looks like a every single micro nutrient deficiency. Indeed those symptoms match at least with Mg, K & boronn def.
Just wondering could that excess/tox Fe have caused all of this?
As PM’d you earlier regarding the tap waters chlorine chlororamine content; most peole who uses tap water here they either let it sit for +24hrs before they use it (chlorines supposed to evaporate in a day) or they pump air thru which speeds up chlorine evaporation.
…Ive never did this before. Ive always just taken staright from the tap to separate 10L bucket and mix everything on it, then fill the res. And after every res change it feels like it gets even worse for a couple of days. Obv theres more pH fluctuations after the res change which may have an affect on something.

Tried to search more about cannabis relationship with Chlorine. And it seems to be a good thing in small amounts ~5-15ppm, but especially in hydro chlorine kills all the microbial growth.. Not sure what it does for the Hydroguard Bacillus bacteria. Could do damage on higher doses for example in organic soil, but theres that much living things so it wont really affect.

Theres couole topics I found about Cannabis and chlorine:

What effects do those chemicals have on plants in general and marijuana specifically? Plants need some chloride, which is a micronutrient, to grow, but too much of it — what’s called “chlorine toxicity” — can build up in a plant and result in browning, yellowing, or scorched-looking leaves. It can even cause leaves to fall off the plant entirely, which, in the case of a budding cannabis, of course, sort of destroys the point of growing it at all. And according to the University of Maryland Extension’s College of Agriculture and Natural Resources

When glycophytes experience Cl− salinity, the tissue concentration of Cl− can increase well beyond its requirements and may lead to toxicity. Visual Cl− toxicity symptoms often start with chlorotic discolorations that turn into necrotic lesions, resulting in the symptom of leaf-tip burning. Symptoms are deceptive because the visual appearance can be similar to those apparent under conditions of other nutrient deficiencies (e.g. Cl− deficiency) or element toxicities. Although photosynthetic capacity, growth and yield are reduced under Cl− toxicity (Hanson et al. 1999, Slabu et al. 2009, Tavakkoli et al. 2010), few attempts have been made in the past to understand the molecular and physiological mechanisms that lead to such Cl−-induced damage. Here, we will review possible explanations that link Cl−salinity with metabolic dysfunctions and visual symptoms. We will also develop ideas that might shed light on this topic.

This seems like it could be even more rare than iron tox.. And honestly no idea if it could be because of the chlorine. And micro nutrient toxicity obv leads to other micronutrient lockout.
Since Ive done so many res changes during this 3.5 weeks (hydroguard, new calmag doses, fresh patches to see if any improvement) there could have been shit lods of chlorine available for the plant.

I'm not sure what exactly Canna Flush is, but I don't think it would be something needed.

It is just kinda acid ”cleaner” designed to help all kind of flushing operations and for example cleaning substrates for re-use. But thats all about flushing, theres IMO many kind meanings and purposes by doing it. Not needed supplement at all, but thought its worth of a try, since needed it for the soil plant as well.
Canna flush does not kill any beneficials or bacteria.

And Ive tried to flush net cup with pH’d water mixed with lil bit of Cal/Mag. Ive tried with straight tap water and also tried with the peroxide mix.
I guess if I just want to rinse the basket and get the excess shit/salts or w.e away from the hydroton, it doesn’t matter if its ph’d or not…IF I dont want the plant to absorb anything from the flushing water.
And after Ive done multiple flushes for the net cup without results, it feels like thats not the case.

And yeah that N% of Cannas CalMag could be a problem later (If we ger there lol). The N dose most likely needs to be calculated from now so I don’t totally over do with it.

Theres been like 2 to 5 days room between each ”experiment” to see if it gets better or worse.
Hah, and the next one will be tomorrow, again… Bought RO water, so going try with that. If it somehow magically balances the nutrient uptake, then Im going to blame the tap water/chlorine. It feels like a last straw for now.

So fingers crossed to help overcome this whole fuckd up situation.

 

[FelipeBlu]

Hang in there, V! It may hurt, but it’s only one grow - and a fantastic learning experience.

10/18 Update | Day 29 | Week 4


Start of the week 4.
Had to ditch the coco BB Kush because she was stunted af and didn’t seem to get better. One trouble less, even tho thats mad stupid to throw away expensive seeds/plants which could always yield at least something, like handful of popcorns, lol.

DWC Critical having very fast veg growth now, even tho the issues remains. Figured out it is not Ca def either, could have been an excess at some point when theres been +250ppm of Cal/Mag… Every affected leave has slightly burnt tips, some of it spreads to the margins. Could be excess P as well which would explain the lockouts/troubles on Ca, K and other micros uptake.
So tried to keep it simple as possible;
- Tap water for the new res ~75ppm of Ca & Mg
- GHE Micro (6% Ca) 0.8ml/l = 59ppm extra Ca, N 49ppm + other micros
- Grow 1.2ml/l to balance N & K ratio
- Bloom (3% Mg) 0.4ml/l = 14ppm extra Mg, Total N: 75ppm, P: 16ppm, K: 81ppm & Cal/Mag about 150ppm total.

Will see if it works…

Day: 29

Blackberry Kush (soil)
Stretchinnnn like no tomorrow. Should dim the lamp to 100% but Critical starts to light stress if doing so.
Fed with GHE pre-flowering recommendations (~1.7EC food)
She looks a bit like shes struggling with Mg uptake (yellow tips on newest growth)
Pistils slowly starting to stack up

Critical 2.0 XL (coco)
She looks tall and flimsy right now. The main stalk keeps stretching even tho its topped. I guess when the new shoots start getting stronger and woodier it gets some more structure.
Gotta add Silica to the feed list from now…
Last couple feeds:
~200ppm of Cal/Mag
- 1ml/l Micro
- 1.4ml/l Grow
- 0.6ml/l Bloom
EC ~1.6 slightly too high, but I guess she would stretch even more with lower EC feed.
No signs of pre-flowering yet

Critical 2.0 XL (DWC)
Newest res mix listed above.
EC: 1.3 (after every res change, no matter what the EC is. she eats something 0.2 EC / 100ppm worth of food from it. Then pretty much EC stays same couple of days.
Now going to up from 1.1 EC 0.2/100ppm every two days and see if she starts to get better. And/or see if any deficiences or excess appears so they could point me the direction.
Res water temp: steady 21C
Humidity: 30-55% (depending what VPD I want)
VPD: ~ 1.4kPa looks like working fine for the Critical.

Slight chlorosis visible, but dunno what causes that and hopefully it gets better now when trying to keep it simple as possible. Might even try lucas formula if it wont start getting better.

Have a nice monday! Safe

Hi Verbalist - grow is ticking over nicely
Just a thought - take 5 mins to cable tie those cables off the lamp canopy, tie them up the hanging wire
Coiled cable touching the lamp will create hot spots in the wire which will increase the resistance at that point, causing the cable to heat further
Put your finger on the cable where it touches the lamp housing - I'll bet it's rather warm
Just sayin' mate
PS Excess Fe can be treated with more K (Mulder)

Hello Growings hope your growings are growing well!
And thank you for the tip! Will definitely look at it when gettin back to the place. @Mars Hydro TS 1000 does not produce more than 25C (hottest spot above the lamp) when dimmed at 75%. But obv if theres a wire touching it creates more resistance and needs to be hang properly. Didn’t realize that at all. Started to think, there might be all the leftover wire lying rolled up on the lamp.

And yes mulders chart says any excess K creates synergism with Fe.

 

[Rexer]

Shes looking so much better.

Here's something to be careful on. When supplementing either magnesium or calcium a ratio/balance has to be maintained. Too high of one mineral can impede the uptake of the other.

She seems to be doing a whole lot better so I'd be careful on making any big changes. She's looking pretty good right now all things considered, you're doing great!

Will be doing a strain 2021 strain review in a week or two

Yup thats why I tried to cut off all the extra supplements since Micro & Bloom + tap water should contain enough Ca and Mg for the newest res mix. And when I do want ro rise up NPK ratios topping with micro and bloom increases calcium and magnesium ratios as well.

She looks better now and the growth being almost unrealistically fast.. Guessing there might be still too much N or too little K, since green grows in eyes but the stems and nodes having hard times to keep up.

The green is a bit dark, but the confirmation (at least that I know of) is when the leave tips turn downwards (almost 90 degree bend) for a nitrogen toxicity...I have it on my Somango Auto right now (pic below). If it happens, it's nothing to stress over, and just means a little tweak is called for (less micro most likely).
The fact that you're thinking that way, shows you've been doing some research and are on track for success

 

[StoneOtter]

Brilliant fe fix for your critical plant Verbilist! I didn't see that coming! Nice to see her come around! New lights are doing fine work! You rolling with the punches!

Thanks for the information brother
Earlier tried in ”a test sense” to feed coco Critical first then DWC with GHE recommendations (a bit higher overall NPK than right now) the coco Critical showed excess/nitrogen toxicity as mentioned in my previous update (days 24-25) but DWC Critical did not show same kind of ”clawing”. But instead of clawing these symptoms were more present: dark green foliage, slight burn on the tip of the largest fan leaves, weak new shoots, weak stems overall and couldn’t keep up with the leaf growth and most likely had effect on nutrient uptake.
So Ive tried to do some research how does excessive amounts of each macro nutrient affect on other nutrients uptake, how do they present the symptoms and do they have synergism with other elements causing more unwanted occurrence.

Found this chart would make sense for me:
Went thru every bottle and calculated the nitrogen nitrates. Cal/Mag agent, GHE Micro, Grow, pH minus are VERY RICH in nitrates. Every bottle has Nitrogen in a nitrate form 70% all the way up to 90% and those remaining 30-10% from total nitrogen are ammoniacal.

Not all deficiencies are caused by a lack of nutrients! For example, Calcium deficiency may be diagnosed due to low Calcium levels OR because there are high levels of Nitrates (NO3). Nitrates ‘push’ Calcium away and can block absorption.

So watching the N antagonism above; too much N would lockout/reduce Ca and K uptake…which would make 100% sense by looking at my plant. Green grows like no tomorrow but new shoots being weak and flimsy, Ca deficiency looking symptoms appear there and there, newest growth (micro nutrient deficiences) looking symptoms etc.

So the best option to do would sound like reduce the N amount, right? Thats not too easy… if I reduce the amount of micro (primary N source) then Im reducing all the micro nutrients including Ca… Okey that would be doable to increase Ca&Mg values from other source example adding Cal/Mag. BUT Cannas Cal/Mag does contain 5.9% N total which has 5% Nitrogen nitrates. So that would be plus minus zero. Or even worse in worst scenario if the amount of nitrates just increases if theres two sources instead of one. Do you follow me?
So being said there is too much N available, excess N reduces other nutrient uptake and excessive N fucks up the N&K ratios…even more if theres excess and it has negative effect on K uptake.
Nitrogen being the easiest macro nutrient to absorb and it absorbs from 5.5 all the way up to 7pH for example. So there most likely wont be a situation where plant would have problems to absorb N, compared to other nutrients.

This is the most reasonable thing I come up with. Also DWC Critical being between week 4-5 and no signs of pre-flowering (in my understanding too much N delays or could even block the start of the flowering).

If @FelipeBlu could confirm that Im on the right track would be great! Dunno if youre still on the road brother and have no time.
Also thinking about trying the lucas formula to achieve about 1:2 ratio of N&K, but idk if increasing Bloom (0-5-4) would quickly skyrocket the P values(?) And what would be the max ppm for the phosphorus at this stage to avoid any further lockouts or nutrients excess

 

[Verbalist]

Brilliant fe fix for your critical plant Verbilist! I didn't see that coming! Nice to see her come around! New lights are doing fine work! You rolling with the punches!

Hey Otter good to have you back!
Yeah I guess excess fe or tox being solved by now. Feels like it is hard to find a good balance in nutrition using DWC or then the plant might be very nutrient sensitive, or the excess Fe having still negative impact.. Hard to tell

But true dat TS 1000 were real worth of budget upgrade. It is doing great work and feels perfect for that small tent.
