You can top whenever you want and it will stay shoter and wider. The FIM method works best fer making it fuller. You just cut 3/4 of the top instesd of pinching off the whole thing. FIM means fuc~ I missed!
you cant go wrong either way....... bend it down and more shoots will grow = more clones......... or cut it..... ive cut mine in half..its never too late to top a mother your not gonna flower it
