I see. I FIM all my plants, it controls height. you can't really screw it up, its easy. If you haven't seen it check out" fimming with blaze" in the advanced Maj Culv section. I also LST most of my plants, low branches with lossa buds.Nope. Didnt do any sort of topping or fimming. Since this is my first grow, I really didnt want to take the chance of screwing things up.
