Calcium Deficiency Won’t Go Away DWC
Cali_Grown_420started grow question 4 years ago
So plant #1 is still having some Calcium deficiency issues. I’m using RO water and giving the recommended dose of CaliMagic which is 1tsp(5ml)/gal. I’m in DWC and using LED full spectrum lighting. Why can’t I stop these spots? Should I give more than recommended dose of CaliMagic

I'll elaborate what messes with a lot of people is that there is actually and excess of calcium and almost all cal mag formulas are formulated with nitrogen for Transportation except 1 that I know of.. Anyway Cal-Mag is gathering dust on my shelf.. I grow everything all strains with a lot of intense led light...

Hello Cali_Grown_420, I've had a little bit of experience with DWC and I also have incountered this problem maybe I can help, I don't think its a CaMg problem what are you running your ph levels at.

Honestly looks like a pest problem to me. Have the same issue happening with my 3 blue kings out door. I've got a plague of pests this year. Ordered some nematodes try and solve the soil issue, tobacco spray for leaves.

Stop using Cal-Mag.... It's a coco thing.. Believe me or not.. I don't care.. I grow plants... I didn't read books now I am, interesting stuff ... I grow trees and a lot of the reason is because I stopped believe stupid secondary bs... like you need water chiller.. and you need this and that... all this is... is your triple formula has all the calcium you need. you keep feeding cal-mag if you want but it's absolutely 100% not needed for a lot of growers.. EXCEPT COCO growers..

Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

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.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Autos reacting to All-Mix: Slight nitrogen overload?Pheno one showed very "leathery", weak, hanging leaves of dark green. Same time the fungus gnats had a run and the population doubled. After second LST also the stronger plant showed those signs on the younger upper leaves. Also curled down a little. Slight nitrogen toxicity?

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!
