@Patauto124, do you folier feed? As to the early pistils, is it just showing sex? Have seen several posts of autos showing that early.
Only issues I've personally had with tight growing conditions, it's a pita to water, and you need good air movement to help with humidity... all that green inclosed can make for a sweat tent. If you've got good ventilation, and fans above and below the canopy you may be fine. Personally, as they mature, I'd keep the closest to harvest at the front, allowing for good inspection and additional care without gymnastics.
