Yellow lower leaves on 8-9 week old plants - Deficiency or age of plant?
Lower leaves are starting to yellow on some of the plants. I think I have corrected my cal/mag issues but now these yellow leaves. Going into week 9 of flower. Is this normal because of the age of the mature plant or a deficiency? Or is it still cal/mag deficiency?

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.

What to do? Leaves are getting worse.
Had some light strain earlier on, but now im leaning toward a deficiency. Been feeding on a low-dose flora series schedule with clean ph water for every other feed. Just had clean water yesterday and nutes 3 days before. Dry out between feeds. Nitrogen? Calmag? Other?

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.
