Withered leaves

I have 2 plants, one is fine, and the other as withered leaves.
I grow in autopots, coco perlite, air dome at the bottom of the pots with air for 18h/day.
It’s a FEM Blackberry OG CBD, in a tent with a spider farmer 1000 at 24" high.
My plants receive Remo nutrients (micro, grow, cal.mag, velo kelp) and I’m using the nutrients calculator on their website

Anyone can help?



How often are you watering? They look over watered

Welcome to the community @FatMike55 , I agree here, those leaves look heavy
