I would maybe wait a bit to put plants outside since the day length might be a bit too short, time the daylight hours and check. Going back and forth from veg-flower has potential to make a plant hermie. I wouldnt put anything outside yet since theres still a lot of frosts at least where Im from. The autoflower doesnt need a 12/12 photoperiod to flower alot of people seem to have them do well with 18/6 or 20/4.
