Dang bud probably should have researched a little more about growing autos. Topping autos isn't good and probably will take a couple ounces off your final yield. Autos start flowering around day 30 no matter what's done. So taking that top off stripped that main bud site. Train autos with cropping or lst even trellis. Top photoperiods, photoperiods only start flowering under a light cycle of 14.5 hrs or less. That allows you to keep vegging photos allowing them to heal and grow before flipping to flower
Could benefit from a better light as well. Lots of stretching, lowering your light during seedling stage and raising it as the plants grow aids in that.
