So this is why autos are flakey at best and serious growers tend to not use them. Veg or flower cycle does not matter, these plants will flower even when given 24hrs of light. That’s why they are called autoflower. Not only are they impossible to predict the yield is often sub par in my opinion. Next round do yourself a favor and get some regular or feminized seeds. Autos are really just a gimmick and tend to be a waste of time and effort. Good luck 👍🏻
