ive had as pathetic as 1/2oz from 4 underlit plants in horrible, nutrient burned conditions (oddly-they produced some of the best bud ive smoked, and only 1 viable seed which is currantly a mutant)

and as good as 2oz per healthy sativa plant under a 600w hps

im still a noob grower though-but im learning

PS: about the mutant seedling: its about 4 inches tall now, and its leaves have about 3X the surface area of any of my other seedlings that sprouted earlier and are being now dwarfed. also, its got 2-3cm branches on it at 2 weeks since sprouting. IS THIS AT ALL NORMAL?
