leaves in the way too much shouldnt be cut unless they touch the soil just use bread twisty tie type material or coated paperclips to pull leaves outta the way Good Healthy Leaves = food for nugs to make them larger. anytime ya cut rip or tear the plant in any way shape or form this causes undo stress on the plant. it slows production and starts repairing if a leaf looks dead then gently give it a gentle tug if it comes off it's yours, if there's any resistance it really should stay untill its ready. a yellow leaf still offers the plant a means to transfer sugars during photosythnisis . and if your not in flower and your vegn and have yellow/dead leaves something maybe up w/your soil PH if leaves yellow during veg check PH. if they yellow mid way through flowern probably wasnt enough N during the 1'st few week stretch of 12/12 if soil PH is fine.whitebubba said:due you mean prune or top? prune you would cutt off dying leaves , and leaves in the way too much. Toping just cutt of the top of the plant above the last set of leaves. Cut of the entire top above the last node.
