I remove all branches that won't get buds into the light so focus can be on the ones in the light. I probably leave too many.
I also remove all leaves below the canopy that cannot get light and that helps heaps with air flow and a bit lower RH. Key to removing these is timing and a major defoliate and trim could be done a week before the flip to allow for it to recover then focus growth to the bud sites. I also trim after stretch but no more than 3 weeks after then I just do minor stuff, leaves that are wet, dying leaves on buds and lower, leaves covering bud sites, etc.
This grow I removed quite a bit a bit late. This seems to have slowed bud growth a bit to a lot..but I've also got a bit of N toxicity going on which really knocks back bud development...can stop flower growth entirely, but not in my case.
