Con el amarillamiento de las inferiores, tambien podria ser falta de N. Revisa el PH que no sea que te bloquee alguno de ellos.

Does the paleness concern you?
Plant #1 seems a bit more on the pale green/yellowing side of the spectrum. Especially compared to plant #2. I have been feeding this week on a gradually increasing schedule. Not enough characters to go into it here.

Calcium Deficiency ?
Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Calcium Def/Wilting or other issue?
So after 24 hours of feeding it CM Plus it doesn’t look any better. I’m hoping there is not another underlying issue. Environment remains the same. Pics are 24 hours apart. Or will it take a few days + before seeing improvements?

I have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.
