These Bruce Banner #5 Fem plants stretched 3 x the size after switching.. 630w lights were at 100% 1st 2 weeks of 12/12 now @ 80% for last 2 weeks

pick a spot and do some targeted damage to stem.. gently, as you can. snap it between finger and thumb, but do consider the direction you snap it toward. May need support the first 24h, but after that you more likely need to tie it down than up. It will try to course correct otherwise. So, bend into unused space or be systematic about not criss-crossing with other branches you also need to snap down. This is HST or supercropping? doesn't matter what stupid name was made up for an existing method of plant training.
