The answers you are looking for are very subjective. You can do as much, or as little, LST as you like. Also, you can stop whenever you like. You probably donât want to be doing much training in late flower when the branches become more rigid.
Also, I looked at your diary. If youâre really on week 9, Iâd recommend switching your lights to 12/12. With an auto you should be closer to harvest by week 9 than to preflower (youâre not in flower yet). Iâve had this happen before myself. The good news is sheâll be a monster plant when sheâs done!
