You water them very little and don't forget to add some mycorrhizal fungi spores if you haven't done it yet. Then it's just waiting and observing.

Good first journal Amy!
Late to the show, but glad to see you are doing an outdoor grow. Taking a seat, good luck!
Peace

I wish I was from somewhere else so my neutrality wasn't an issue (people get upset sometimes when I applaud other teams!)I love Cricket too Amy, Elyse Perry is a fantastic player. I love Test Matches, so many variables and twists and turns over the course of the day. I am hoping to get dowm to the MCG for the Test, I have been a couple of times since I moved over. Being from N.Ireland I am a neutral, I just want to watch a great game. Ireland play as a united team, which I think us wonderful - Sport transcending boundries and rivalries. They have been given Test Status, so hopefully I can finally watch Ireland play Cricket. Hope you are having a great weekend.
Ooooh, and tests... no better nap than after lunch on the 3rd day, not a lot of action on the pitch, deep voiced commentator quoting obscure stats & mentioning Brian Lara....
Thanks Gee! they really were on that day - and even the days following.Plants are looking gorgeous Amy
I agree with up potting, what I see is fade starting at the bottom which would indicate nitrogen deficiency and the brown spots down low which would be a PK issue. I'm thinking your mixture of soil and coco isn't holding enough NPK. It's behaving like a super fast draining soil and isn't retaining a lot of nutrients.
Hi all, today I'm seeking assistance with diagnosis and advice re possible mineral deficiency and how to address it. I could be chasing my tail a bit... please bear with me as I lay out what I've done (it covers some of what's been journaled already, just to save anyone reading back...)
To set up: the medium is currently less than ideal and totally not what i'd planned them to be in at this stage. But, well, things happen in life and projects don't always pan out as expected, which effects other projects... The upshot of it is that these poor babies are still in a 50/50 mix of seed rasing mix and coco coir. They're at about 4 weeks from seed, outdoors, give or take a day or 2. The pots are about 5-6inches high and 4ish inches wide.
The things I have added to the medium;
- Mycorrhizae (AMF): 0.05-1tsp sprinkled and watered in when they were a few days old, plus a tiny sprinkle more 2 weeks later after rains.
- Powdered Gypsum: sprinkled 1-2tsp each around the pot when they were a few days old, and again about 3 weeks later (a week ago).
- Aloe and Kelp Ferment organic liquid fert. (contents listed below): I make a very weak tea with this - although I'm mixing it with such a little amount of water (just under a litre) at this point it's hard to be sure. They say 20ml per L, and it's hard to measure just one ml. to make it an even weaker mix than that (seeing as they're young - maybe I should be making more quantity to be sure I'm not making it too strong). The first feed was 10 days ago, second feed 2 days ago, (used the dunk&drench method for 2nd).
- Neem cake - about 0.5tsp as a top dress 10 days ago
- Mushroom compost: a bare sprinkle as a topdress 10 days ago
- Epsom salts: about a tsp or less scratched into the surface of the medium, about 4 days ago:
- Iron chelate: 0.5g dissolved in 600ml and watered in a day after the last 'tea' dunk & drench.
- H20 - our water is rain rain water (sometimes the water we've boiled 4 eggs in - tip from AKGramma for calcium). Used every time i referred to 'tea' or 'watering in'
As I'm writing all this I'm thinking - gosh that sounds like a lot, esp of potential N fert (the neem has it, the compost would have it, the 'tea'...) so maybe what I thought was a super light touch is actually too heavy. All are at super small amounts - I think.
Anyway, the organic liquid fert. has this in the description and I'm using it to make super dilute 'tea'. Not sure I can link to the supplier, they're not a sponsor. They sent it to me as a freebie with my minerals - good on them!This fertilizer contains the following variety of microbes.
- Rhizobia (Brayrhizobium Japonicurn)
- Azospirillum
- Aspergillus Niger
- Lactobacillus
- Pseudomonas Putida (P-Solubilizing microbe)
- Bacillus Subtillis (P-Solubilizing microbe)
Also Contains: Salicylic Acid to boost the plants immune system, and Saponins for IPM and soil tilth enhancement.
N - 1.67%
P - 1.38%
K - 1.36%
Ca - 4.39%
Mg - 1.54%
S - 0.993%
Amino Acids - 3.05%
Contains trace minerals - Boron, Zinc, Manganese, Iron, Copper, Molybdenum, Cobalt.
Derived from - 80% Aloe, 20% Kelp, Humic Acid and a Variety of Microbes.
Some of my reading tells me that Cal:Mag ratio is best around 6-10:1, so the way I see it - and please correct me if I'm wrong - that 'tea' I'm making doesn't have enough calcium in the mix so it's a good thing that I'm trying to supplement that with the Gypsum (and boiled egg water).
Q: I've been told that top dressing with gypsum powder, or adding it to the water, will make calcium available fairly quickly. Can anyone confirm or deny that?
For the most part they have been looking super strong in stature and sturdiness. There's just been some fade issues, and then today some worse ones (hang wit me please, I'm getting to that). At first it had the appearance of mag def - with the fleshy parts between leaf veins were fading (worse on the CBDCC), hence the use of epsom salts - and also a general paleness. I noted this in the last update a few days ago. This patterning is not as noticeable now, on any of them.
Q: Is that too soon to have responded to the epsoms - like 3 days?
Then, a couple of days ago (the morning after I'd posted my most recent update) I noticed they were super pale, to yellowing, from the centre of the growth zone outwards, in an even gradient. This is a group shot of them then, followed by a close up of the MB, it is the next day after their 'drench':
Fade is hard to see in pic, it was way more pronounced in person. but was worse on the MoneyBush, 2nd from the left (80%Afghan indica x 20% cColumbian/Mexican skunk if that helps) but is maybe is easiest to see on the CBDCC, 2nd from the left. You can also see the fade to yellow on all the lower leaves (baby leave are pretty much dead).

MerryAnna - I know you said they can do this (sprout pale new growth) after the rains, so maybe that's all it is, however... they were fading all over a bit ...
I looked it up and it seemed to match iron deficiency pattern so this is when I gave them the iron chelate. There's literally nothing in the medium except what I've put there so without the whole bottled notes thing, like a full (planned) coco grow would be using, I'm trying stay on top their needs, in an unknown medium while knowing little (oops - not really a recommended trip for a novice). I'm really trying to do a grow with mucho minerals and minimal ferts and to learn about how the plants respond to different things. I'm certainly seeing some of that with this almost coco thing i've tripped into (however temporarily). (Don't ask me why I started them in the 50/50 coco/SRM blend - it was suggested as a good gentle starting medium and I thought it sounded like a good idea as my soil wasn't anywhere near to being mixed even.)
It seems to me that they respond really fast - like to the epsom, as I was wondering about above, but then again to the iron chelate I gave yesterday morning. I swear they look heaps better on that front today - less fade to the centre and deeper colour in general.
Q: is it possible they'd respond so quickly to the iron? Could this fast response (if I'm not imagining it) be due to the 50%coco coir in the mix?
This is them today (except 1, there's a whole different problem with Prof#1 today, more on that after this)
Money Bush - day 29
CBDCC - day 28 (left) + Prof #2 - day 26 (right. It's bit stunted, has been getting more of the harsh winds maybe - smaller pot too).
So not too bad - but I feel I am very close to the edge of them not being ok. Is it novice grower neurosis? Maybe - but I don't actually feel neurotic about it all. I'm just detail obsessed. And actually really interested in everything that's happening. I am enjoying learning so I'm not panicking about any of this. I do want to get them all through this though and have some kind of a harvest in 3-4 months!
So now, finally, we're at today's "event": While Prof Chaos #1 also looks a bit recovered in the fade department - she now looks like this (pics below): Ca deficiency? and Mn def. spot on one leaf as well? - This is the only one showing any of this so far, and it's only appeared today. The browning off seems isolated to the 2nd pair of serrated leaves, can't see it on the others. The Mn(?) spot is on one of those 2 as well. Those 2 have a clawing going on as well - rest of the plant(s) have no claw.
in general, apart from this, the stature and strength is still good and the new growth looks ok.
None of that was visible yesterday.
Maybe I'm chasing my tail here as I'm try to coax them through in a medium that's probably more like growing in coco coir - which I don't know much about except that it's like soil for hydro, needs feeding a lot and requires a lower ph. That last would be a problem b/c my spike says it ranges from 6.2 to 6.8. I wouldn't normally be overly concerned about ph - but the abundance of coco coir in the current mix makes me wonder.
They were never meant to stay in this medium so long. I thought they'd be in soil two weeks ago. I'd like to be able to say now, with confidence, that the soil locations will be practicable in at least 2 weeks but I can't be at all sure! (I'd thought that 3weeks ago - lol).
Q: Should I just be doing whatever I can to put them in a nice soil mix now? (I.e., forget about optimising root development - which may not be happening in the 50% coco mix anyway.)
One plan that I could possibly execute, would be to (firstly) get over not wanting to transplant them more than once and get them out of the current medium now and into pots about twice the size, with a good soil mix in, and then transplant again into their ground based soil beds just before flower is due to start (around Christmas I think). That would be in about 3-4 more weeks.
If I don't do that, I can really not see them in a soil home for another 2weeks at least.
I'm seeking insight and advice from the illustrious collection of growers I've been lucky enough to meet round here - particularly about the deficiencies i talked about, but also about next possible forward steps.
I know it might sound like I'm super worried and stressed about it. I have concern, that's for sure, but I'm full of enjoyment for the process. Please help me not to kill them though, please
thanks fellow 420ers
I grew in LOS so that I wouldn't see those deficiencies...
You build the soil and then you let the soil feed the plant.
... You're reacting a little too quickly, IMO Amy. Small changes over time. It's so easy to look at a plant and want to do something NOW! when it may be more beneficial to wait it out and only change one thing.
I support your inclination to upcan. They may simply need more soil community under them to get the balance necessary. Organics and small pots don't work well.
increasing the root zone ... usually does the trick in living soil communities. Your girls are looking pretty good from here. New growth is what you want to keep an eye on, and yours looks healthy to me.
Good luck Amy. They're resilient plants.
I agree with up potting, what I see is fade starting at the bottom which would indicate nitrogen deficiency and the brown spots down low which would be a PK issue. I'm thinking your mixture of soil and coco isn't holding enough NPK. It's behaving like a super fast draining soil and isn't retaining a lot of nutrients.
Hey Amy
... calcium deficiency do they look rust spots ?
Magnesium...?
The claw ? Ph at that stage should be around 6-6.5 I would say lower to 6.3ish
Hmm .
Are you growing outdoors right now? Some of the damage looks like a combination of nute burn (maybe from splashes when feeding or over feeding) and insect damage. High heat will do that, too. Another possibility is nute lockout from feeding too much nutes. Nute lockout from overfeeding means that the plant cannot absorb essential nutrients.
Nute deficiencies generally affect specific parts of the plant, not on just a couple leaves here and there. Your new growth is the best indicator of the health of your babies.
Someone else suggested this too...Safest treatment is to do a plain water flush, and wait another week before you fertilize again. As with all living things, plant or animal, too much food is not a good thing.
