Don't listen to anyone who tells ya to defoliate or top your autoflowers, they're on their own short clock and if you defoliate or top, you'll take vital time away from the plant to produce new growth, if it takes 3 days to recover that's 3 days lost. Take it from me, I grew 1 pound autoflowers more then once in my life and I'm telling ya let the be, you'll thank me late.
