id say overwatering, also. let the soil dry, and see if the leaves perk up. raise your lights an extra couple inches to take less light stress to overcome the water imbalance
i would tuck any growth thats shading a potential flow-producing branch then make your decision as to how many branches you want, accompanying your main cola. also, i like to clip any internodal growth 2-3 weeks before the flowering 12/12
bury the pots if theyre in pots, dont plant them in a very open spot. Make sure it gets direct sunlight but make sure it's still ducked off. Plant them in odd patterns. Dont lay it out like a grid or anything
how are you smoking on it when you chopped less than a week ago? you must be smokin some green azz shit!
also, why are you telling us the "weight" of your yield, when its obviously still way too green and wet to give an accurate weight.
pretty sure fan leaves during veg. state wouldnt hurt unless, like these guys said, it was just a ridiculous amount. But really, too much of anything isn't good eh?
