Ch33cHanswered grow question 4 years ago If its outdoors and you have no height issues i would let her grow big and thrive without the topping. But its really not to late to top at all. It depends on my times but sometimes i will just top right before 24h darkness and flip to 12/12.
If you wanna top her and shes outdoors then this is best time for you to top as your days are running short till flowering.
