I don't think it'll harm to the plant, but the buds will get extremely leafy, leading to an extended stay in trim jail...Regarding the un-needed N. Will it do any harm to the plant? Or would it be just a waste of N?
My Chocodope got a big jolt of N in flower, and that's what happened,(besides greening it up) so I'm guessing more Dots might do the same thing.
