I'm starting to notice yellowing of leaves almost daily now on a Critical XXL scrog grow. She is 5 weeks into flower, had a rough (cold) start, and has always been a bit stunted. I was worried I'd overfed (3ml / l biogrow) so scaled back for 2 weeks. Is this normal?

Deficiency or light stress?
I start by saying that the light was not close enough to cause stress imo.. was about (30cm) of distance from this plant. it seems that it is more a deficiency in my opinion but I don't know exactly which one.. What do you think about that?

Curled leaves
Why my plant's leaves curl up like that? I think that there's an overwatering issue, but is there any way that my soil is not good?

My dear fellow growers, I've just started growing with no experience and am experiencing some leaf issues. I'd like to ask for your help and sugg
The plants in the photo were planted on August 15th, and they haven't bloomed yet. I have very little knowledge about fertilizing, so I applied fertilizer every time I watered for the first month. I'm growing 9 plants in a 120x120cm tent and using two 240W full-spectrum lights.

Brown spots, PH in run-off is in the high end (6.5~)
I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?
