I consider myself as a newbie. I always top everything that pops out. There is ways of doing it that you can make the plant grow in a predictable way. I never got there. Theres been some I only topped when it was young then let it go. I don't know??
I topped the main stem about a week ago two new ones been grew back strong and beautiful i was mainly talking about topping the others dont think im going to like you said less stress but i have seen people top their whole canopy
Thx man first pic is some barneys farm blue cheese second Humbolts 707 truthband and in the back i have a Purple afghan kush new from dinafem and Bubbas gift another humbolt
I like to experament, id top half of them and just LST the others. I topped both of my OG kush twice and did some minor LST, so far the results are good in my opinion. Only 2 weeks since flipping to 12/12 though.
