My auto's just started pre flowering a day ago...the little hairs/pistils are coming out. By this, I assume that the plant will not be growing anything more from the top except the main cola? No more new leaf growth? My main question is..if this was a regular seed..then would the plant just keep growing new leaves from the top as long as I keep the 18/6 light schedule? Or do regulars also hit a 'top' and wont grow newer leaves and just start to shoot out pistils?
