Auxin might be the hormone you're after. I avoid those issues by not going too wild with training, etc. 2 weeks after transplanting clones they are usually about 8"-12" tall and have ~5 or 6 good branches. I'll remove the very top growth tip (apical meristem) and this causes the other branches to be able to grow faster. The auxin in the apical meristem causes the lower branches to grow slower and to have that triangle "pine tree" shape. When you remove the apical meristem, the auxin lock is broken, and those 5 or 6 branches can bush out and will become the main branches that hold the monster colas. I remove the apical, transplant into a larger container, and flip to 12/12 all in the same day and haven't really had a problem with bud consistency. I also don't allow any leaves or flowers to grow too far from the top of the canopy, anything that is or will be lower than ~18" from the canopy top is removed. For various reasons I am also a fan of growing many smaller plants instead of a few larger plants, so keep that in mind.
