Discussion moved thanks @toastyjakes
I ran across a technique in this video (start at about 1:30 to skip the stoner session)
Building massive buds/ backfilling your buds.
This is done for the same reason you top in veg but for flower. He trims about 1/2" off the tops of his colas about 3 weeks into flower to encourage the buds to back fill on the branch. Anyone else done this? results? I see shit I’m always asking for confirmation first. Reasons not to? I see his logic here and he certainly seems to know wth he is about.
