Too little calcium in early flower?
timber03started grow question 2 years ago
I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed.
Is this a calcium deficiency, and if so, how can I address it?

Calcium and Magnesium work together and a deficiency of one can cause a problem with the plants processing the other. Epsom salt from the corner store is good for magnesium and if you boil some eggs eat them but save the water for 24 hours and use it as a foliar spray or simply water with it for some calcium

looks like a calcium issue to me, with hints of magnesium.
No idea whats the NPK breakdown of coconut water power is but guessing not a lot of Calcium as the label did not say on their website.
May also want to update your diary with more information on feeds and how much your giving them.
try and get the manufacture to give you a proper NPK breakdown and all other micros in the products.
If they cant, maybe time to find a new brand.
Good Luck!

Perhaps not calcium but magnesium. Since Cal-Mag is the likely fix it will cover both bases. Last year I ran nutes on Sundays and Cal-Mag on wednesdays, since the imbalance often swings like a sine wave as the chemistry of things runs it's course. If it's locking up, you will see it in the PH of the soil and the runoff after watering with pure 7PH RO water or a bottle of 'distilled' water from the store is even better, as it will counteract whatever is buffering you.

Nitrogen Toxicity?Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).
