I dont know how much daylight you have where you live. But im getting about 13 1/2 hours of light, and thats enough to induce flowering in most strains of cannabis.

You put them outside too early, or you gave them a different light schedule to sudden. Another month and a half and you should be fine to put them outside,


Ide get different clones because your plants are going to get stunted really bad because as the days get longer its just gunna re veg itself. Thus theflowering, then vegging, then flowering again is going to really fuck with your plant.
