Deficiency when starting to flower clones

Hi All!

I include pics of my clones 2 weeks into flowering, they developed a pale green color, and show some strange yellowing and other deficiency symptoms. Any exper advice and opinion is greatly appreciated.

First its a plant, cloned, vegged for 14 days, put into 3L pot with Canna Terra Pro soil, getting Canna Bio Vega for the first 2 weeks, to help the rapid growth. Temp is in range of 23-27 under 400W cooltube with 3000K bulb. Watering every 2nd day with Bio Vega, 25ml/5l of 6-6.4PH water. Watering when they start to drop a little bit, to prevent overwatering. Most of them look like this now.



2nd is in flower since 20th december. They are getting their week of PK13/14 from Canna, and also Canna Terra Flores, 25-30ML/5L every monday-wednesday-friday, sunday they get only clean water. Almost same symptoms, but buds form at a normal rate, just I'm worried about this problem, i think it's too early for leaves to use their N stock.



I await any and all opinions. Thank you.

Looks like a P-def to me, I suspect this due to the necrotic lesions forming on the edges of the leafs and the chlorosis. Make sure that your pH levels are stable (6.5 +/- 1) before feeding with any additional nutrients. Also, it seems that you are doing foliar feedings still; I would recommend stopping the foliar feeding once flowering begins because bud sites will withhold the moisture and that is just a setup for mold and disease.

Thank you for the input. So u suggest to keep PH at 6.5? I might try that, although the Canna feeding schedule advices 5.8-6.2 I was also thinking it to be quite low. WIll see. As for foliar what u see here on the pics, is the freshly sprayed neem oil before the girls went to bed. As a precaution only. I never foliar feed. Thank you for the advice anyways.

Cheers.

your plants are not deficient
those are healthy green leaves
look at your new growth - hell look at your last several waterings of healthy growth

you may possibly have had an issue beginning several waterings ago, but i think you've definitely corrected that by now

that's prolly frought stress dude
you don't let your medium shrink before you water for healthy plants
you don't let the leaves get all pruny and shitty either
feel how light that plant is when your soil is all pulled away from the pot edges?
now water it to runnoff - wait 10 minutes - water to runnoff again
now feel the weight of your pot
when the pot feels about 1/2 to 2/3 of the way to dry weight, water

now pinch off those damaged leaves
keep doing your nute/water the same as before and you'll most likely not encounter any more of that issue

if anything, i'd use just phed water for next water - maybe 2

edit: drought stress not frought stress - sorry, but i could hear the trolls atriptrappin
