Help me confirm this Calcium deficiency diagnosis?
val95started grow question 2 years ago
I'm not quite confident in my ability to diagnose this using the charts you find online. Can someone confirm this auto in DWC (pH=5.68) needs some more Ca?

Looks like it to me, but I also see some leave affected by pH going out of range. Try bringing the pH up to 6 and see if that stops the Browning. If your pH gradually goes up then start at 5.8 and correct it back when it reaches 6.2. if your pH gradually lowers start at 6.2 and correct at 5.8. This will ensure your plant hits all pH ranges to absorb everything.

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.

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?

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.

Epsom salt as fertilizer. Whats your take on this folks?Epsom salt will not release hydrogen ions in water so my guess is that it will thus not affect PH. Making it a nice controllable source of Mg that would be not negligible right? How effective would that be to treat Mg deficiencies? Anyone has experience with this?Feeding. Deficiences
