Heres what i been doing,
top em when they are about 8 nodes tall at the 4 the node. clone the cutting.
tie down the 4 branches to get her bushing out.Then i super crop the branches back down over it right as flowering is about to start to level the canopy.
I always use my thumb nail to keep it from snaping,
keep cloning stuff around just incase.
I always tie my branches down or tuck em under some leafs or they willl straighten back up.
