The level of K in the reservoir was getting up there too (+275 ppm) - this will also affect Mg uptake. Pulling the K back to about 225 ppm should help.150-170ppm of Ca in reservoir now, which seem to be too much. 110-130ppm she was doing fine tho. …
Yup - classic Mg def - you would see more necrosis along the leaf tip/edges with K defNecrotic spots appears and spreads interveinal:
Yeah, looks like the tissue burn still spreading. Doing the res change tomorrow and might actually try GHE flowering recommendations. It was around 225 or 235 K, pretty high Mg ~70-80ppm and Ca would be ~115ppm.The level of K in the reservoir was getting up there too (+275 ppm) - this will also affect Mg uptake.

Thanks Krissi for poppin in, there gon be sucha cool plans bout to be executed straight when 2022 startsLooking stellar this way Verb!! Have a great New Year weekend!
Ooooh how exciting!!! Thanks Verb!Yeah, looks like the tissue burn still spreading. Doing the res change tomorrow and might actually try GHE flowering recommendations. It was around 225 or 235 K, pretty high Mg ~70-80ppm and Ca would be ~115ppm.
Have a super blast new year sensei @FelipeBlu

Lil peek:
And You too @Krissi1982 have a great New year!!!
A quick New year update:
- Water level down almost 3L overnight.
- prev ppm: 800
- current ppm: 820
- ppm adjusted to: 860ppm (res change tomorrow)
- pH keeps fallin down to 5.5 time to time / keeping it pretty steady 5.9-6.1
All the 420 fam and grower folks have a great New Year!
Do not forget your new years resolution & wishes

Good afternoon @Verbalist from snowy Canada.1/6 Journal update
+ new reservoir patch
Howdy 420 fam and growers! Greetings from cold ass snowy Finland.
Been kinda inactive lately and Ive got a lot to catch up with!
Now pretty much the new project + side cabinet project finnished, and ready to be executed! More about those later.
First of all looks like I might have to chop the dwc plant after 13 days… *BIG SIGH* Apparently landlords doing a plumbing and ventilation inspection for each apartment in this flat. And Ive got not place to hide that big ass plant. Also my tent being hooked to the house intake vents. So I have to take the whole tent down etc.
Still figuring ways how I could postpone it week or a two at least.
PP#2 on dwc still having issues with Magnesium uptake.. The deficiency or lockout still remaining.
Couple leaves still showing the symptoms. They ending up like this; Finally tacoes and gets crisp to touch.
I mixed a new reservoir patch and reduced Calcium and Potassium ppm’s even more, incase that would fix the deficiency. Newest patch is close to 3/4 strength from GHE’s recommendation.
New mix is:
- 1.1ml/l GHE Micro
- 0.6ml/l GHE Grow
- 2.2ml/l GHE Bloom
- 0.55ml/l Remo’s Astro Flower
- 0.45ml/l Canna’s MONO Magnesium
Gives me:
N: 101ppm
P: 71ppm
K: 185ppm
Ca: 63 + 19 tap water (82ppm)
Mg: 71ppm
S: 127ppm
Dropped Terpinator completely out for now since K is 185ppm already (might top with terpinator time to time), and there is shit loads of resin on top the sugar leaves. But flower development is lacking. Because of that tried to increase Phosphorus and Magnesium, plus they should have a synergism together.
Meh, first time dealing with the flowering plant and dwc. Not sure at all what kind of adjustments I should do. She is still eating shit loads of cations. pH tends to fall down to 5.5-5.3 before Im there to adjust it back.
Can’t even remember when I last time had to adjust reservoir pH down.
1/5-1/6/2022
- Water level: Falling over 2L every 12h
- Prev PPM: 910
- Current PPM: 850
- Adjusted PPM to: 990 (topped with nutrient solution + 1.5ml Canna’s Magnesium)
- Prev pH: 5.9
- Current pH: 5.3 this morning, yikes!
- Adjusted pH to: 6.1

And then we got PP#1, Logan!
Shes just swelling there. Gave her last watering (pH’d water only) yday. She will go down as soon as she has completely droughted. When the whole plant wilts and looks like it has absorbed every drop from the soil.
Thats it for now.
All the feedback, opinions and tips are welcum!
Thanks for stoppin by

Evening Bill. And thanks for the reply!Good afternoon @Verbalist from snowy Canada.
Hope you are well my friend.
Great update.
Sorry about the inspection problem.
I’m using GHE’s Floraseries AKA TriPart nowdays.Re: your c-m issue
I read you mix.
Cal-mag was listed last.
Is that your mix order?
Calmag must be the first thing added to your plain water.
It's important for proper nutrient uptake.
Give that a try you will see an improvement.
That is actually Canna’s MONO-series pure Magnesiun supplement. Its 7% MgO and 13% Sulfur trioxide only.Cal-mag was listed last.
You don't think 5.4 is a touch low to start 5.7 I'd think but thats just me.Evening Bill. And thanks for the reply!
Yeah that sucks d, big time… Makes me actually sad if can’t finish this plant properly.
Planned the next growth already tho. Probs growing 2x NL or GG autos on DWC. And partly started the cabinet grow 1x Tangerine Dream auto in mini DIY DWC. So at least one more round before the spring! …Hopefully…gott shhs shhs not to jinx myself.
I’m using GHE’s Floraseries AKA TriPart nowdays.
GHE Micro for soft water has 6% Ca, so not using any additional Cal/Mag supplements in my feeding regime. Couple times fed Canna’s Cal/Mag agent to bump up Ca & Mg values.
And if not using Silica, then I always mix Micro first so Ca goes first amongst with N and other micros. Then 2nd is bloom which provides most of the Magnesium.
That is actually Canna’s MONO-series pure Magnesiun supplement. Its 7% MgO and 13% Sulfur trioxide only.
This product: CANNA MONO Magnesium (MgO 7%) 1L - growland
Bought the bottle couple days ago so I could rectify the deficiency better.
Don’t know if excessive Calcium or/and Potassium caused Magnesium to lockout. Thats why tried to reduce them even more and up Mg ppm’s.
So far haven’t seen any improvement. Particular leaves getting worse day by day and some of the pistils turning into orange already. Theres definitely something wrong because its producing very little new fresh wait hairs.
Plant should be bulkin up already since all the bud sites has set.
pH pen being calibrated like twice in a week so the readings are accurate between 5.4-6.1 pH, and can’t be pH related issue.
5.4 getting pretty low, but acceptable. Trace elements getting absorbed better at low pH.You don't think 5.4 is a touch low to start 5.7 I'd think but thats just me.
Yes, been chattin about the issue with Felipe. Knowledge ain’t lacking from this sensei.Your rdwc right which isn't my Forte.
Do you talk to @FelipeBlu he is very knowledgeable at this sort of issue.
Maby he can have a look.
I personally keep it at 5.8 always have acceptable results.5.4 getting pretty low, but acceptable. Trace elements getting absorbed better at low pH.
And that could be the one part of this problem, because lower than 5.8 pH Ca & Mg availability decreases. Could try to measure dwc things more than two times per day, so I’d keep the pH in between range of 5.8-6.1
Yes, been chattin about the issue with Felipe. Knowledge ain’t lacking from this sensei.
Dunno if there was an excess of something causing the Mg def/lockout and even if I changed the res, the plants still not absorbing Magnesium. Do I have to do flushes with dwc? Run reservoir with water only for ~24hrs and then get back to feeding?
This is keyAnd that could be the one part of this problem, because lower than 5.8 pH Ca & Mg availability decreases. Could try to measure dwc things more than two times per day, so I’d keep the pH in between range of 5.8-6.1
Thank you again @paintedbudman great suggestion.Bill284 stopped in my grow journal to ask a question related to your CalMag/pH issue, so I thought I'd drop by and take a look myself.
I agree with the others, I try to keep pH 5.7-6.1 ish.
Looked at your recent pictures and the notes. Have you any guestimate on the ppfd levels at the canopy. I'm just asking because I have seen similar things in some of my grows in the past: leaves folding and then apparent nute issues with dead or dying spots on the leaves. I originally though that i had nutrient problems but nothing I ever did changed anything. I'm not sure where i read this but someone commented that too much light can cause nute problems as well as simulate the effects of nutrient problems. I checked my light levels and they were way up there (way too close to the lights, and or too much light in a smaller chamber). Tried to cut back the light level and it helped (this was only a couple of grows ago, so not enough data to be sure but ....) Last couple of grows i limited the light exposure by trying to keep my plants small through some trimming and LST. These showed very little of the brown spots I had seen before. With my new lights in my current grow I am making a conscious attempt to control the light intensity at the canopy to ~700ppfd. Not far enough along on the grow yet to confirm anything yet. Your problem may not have anything to do with this, but I thought I'd throw this idea out there. Great looking plants btw

Yeah figuring out now how fast the pH falls down below 5.8 and Mg availability decreases.This is key
If pH is low - Mg uptake is reduced.
Keep it up!
