Bruising or nute problem?I do not have enough characters here, please check diary for details. Some tops are showing some problems. The thing is, only a few and it does not seem related to light distance. My first thoughts is this is bruising, but I would like some more expert opinions.

Drooping leaves The water pH wasn't right before but it's been at 6 for the past 5 days and the leaves are still drooping and seemingly yellowing albeit at a snail's pace. Water her every 2-3 days + 0.5 ml of feed once a week so not sure what the problem is currently? It's an organic grow.

Nute Deficiency or New Leaves?!Thoughts if this yellowing may be nute deficiency? Or are these just new leaves and I am concerned about nothing and I’m babying them since it’s my 1st grow? Both plants are about to be 2 weeks post sprout. Both are in 5 gallon fabric pots with layered soil (FFHF on top of FFOF)

Yellowing leave tips and clawing down, do I need to start giving more nutrients?Hello all, I'm experiencing some yellowing leave tips on newer growth, it is paired with some light clawing (downside) on the newest leaves (only on the green gelato). I have used very little nutrients so far and have fertigated only once in fear of giving too much.

Upper leaves turning yellow - Day 28 of flowering - Cinderella Jack Auto Only "half" of the plant is doing that. I don't think its a pH problem, the other plants are receiving the same source/quantity of water/nutes. My guess is the buds that are receiving more light are "maturing" quickly and the plant is sucking the leaves close to them. Thoughts?

What am I looking at?Redish Brown spots, and slight discoloration. Magnesium deficiency? Calcium? Other? Gave them a splash of Calmag, but was it even necessary? OR, should I have just swapped nutes and wait, then correct if not improved? (It was nute day, that's why I ask!)
