Like Dee said, but double check everything ! What photoperiod was it under before 12/12 ? I'd do a serious LST and defol that bitch...but not too much defol ! You can still save her, but something having to do with her photoperiod is not in sync. If it's a light leak, it's a big one . Timers fuck up all the time . Peace
So that plant has been under 12/12 light to dark for 8 weeks and in looks like that? If a light "leak" does that I would cut my loses and double check my grow area, the last "leak" like that Noah had to built a boat. Where did the seeds come from?
I dont see any sign of flower, am I missing it.
Go to Growweedeasy.com and read up on what you need to grow indoors.
I have leaves morph into one when they reveg but when they come out of it they seem to usually have 3 fingers. I would cut my losses either way and try and figure out what happened. If light leak is bad enough to do that I wonder how it would ever start to flower.
I have a phantom og outdoors that has been blooming for a while and has never tightened up. Also has produced leaf like crazy. Weather conditions or genetic? Since it is a clone from a normal plant, I'm saying conditions. I think it's conditions in your case too.
I want to thank all of you for your help they're in a grow tent using older G8 led lights one large and two small with two red side lights I think I have got to cut my losses and put them in the recycling the strain is from I 49 PPP-FP4 at least I have new ones coming from nirvana and look forward to a winter grow again thanks
