Hard to see under the grow lights. Try taking a picture with the grow lights off so we can see the leaves proper colour...

Leaves had turned up (taco)
Will the taco leaves go back to normal? I've made the adjustment to light moving it higher and switch the veg light off for a couple of hours and use only bloom. Yes I had a nute issue she doesn't seem to need nitrogen the soil must be plenty.

Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

Struggling with deficiencies (nutrient lockout?)
Hello everyone, I need your help. I've been growing 2 Green Gelato Auto from RQS but I've had some deficiencies for a while now. It's my second grow and it's the first time that I adjust the pH. They are in soil and I'm feeding them with Biobizz liquid nutes at a pH between 6-7.

Small yellow spots
I have small yellow spots on leaves. I want to say it starts at tips and travels down. I moved light away and it seemingly gotten better. I moved tents for bigger space and it might have returned.

Leaf damage/discolouration
The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?
