3 possible reasons. 1. This plant wants more nitrogen or ph levels are slightly too high. 2. This plant is more sensitive to light and doesn't like it being so close. 3. This plant has red /purple genetics and a different "pigment" 🌱👍🌿

CalMag issue. If your giving them enough nitrogen (talking about BioGrow) then this is definitely a calmag deficiency. 😎

Yellow lower leaves
Lower leaves are turning yellow. She just started her second week in flower. My first thought is I'm not feeding enough. She is short, but still a lot of plant here. Here upper leaves are a nice shade of green. She prays all day long. Is this a problem.

Quickly yellowing after possible over watering
That escalated quickly, within 24 hours we have lots of yellowing in lower center leaves on 1 Tastebudz and 1 Ethos: Adding cal mag to next watering. Would cal mag be better or Epsom salt at this point? Would a bloom tea help?

Do these look healthy? Thoughts? I'm new to hydro/growing
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.

We've had some really warm weather the past few days. This morning, just before the lights switched off, i saw it was 31.1 degrees C in the grow tent. Are the yellowing leaves a concern? The yellowest leaves are really brittle. I don't believe they're under-waterd.

Yellow leaves
my little GG2 is starting to lose many leaves (they turn yellow and fall even before drying) while the other is not having any problems (the only difference between the two is the "aggressiveness" used in the LST) it could be due to the flushing done (but less than 5 days ago) 🤔
