These are two different strains - Gelat.OG and White Widow. both have the same problem. First pic it with ambient room lighting, second pic is under LEDs. Plants get about 33,000 lux at the canopy with 4,000k 80 CRI white LED quantum strips. Plants are in vegetative stage with light on 18/6. Plants are older than I'd care to admit. 2 gallon plastic pots with 2/3rds potting mix, 1/3rd perlite.
I think it's nutrient lockout. New growth is pale green, droops straight down, and develops brown tips. Right now there may be a touch of underwatering too. If I water them I expect them to perk up a bit, but not much.
I had real bad lockout earlier where everything stopped growing. I used fox farms boomerang as directed for at least two weeks before things started growing again. I suspect that happened because I was feeding with fox farms grow big, big bloom, and cal mag as directed, but I wasn't watering enough so there's was excess out of the bottom of the pots. So all the fertilizer and salt accumulated. Once things started up again I waited another week (maybe two and went back to fertilizing). When plants begin to droop from dry soil I top water until there's plenty excess out of the bottom.
What I'm planning on doing if no one suggests otherwise is go back to using the boomerang stuff to remove excess salts. If I'm wrong I think it being underfed is a simpler fix than overfeeding.
I look forward to any suggestions you might be able to provide. Thank you.
