Supercrop during VEG and give enough time to recover before FLOWER. Lst you should have already started and you can LST all the way from veg through flower. Honestly its too last to start now as the stalk has hardened and you risk breaking it. however if you do lst, after a good watering the stem is easier to manipulate, and they seem more limp RIGHT before light cycle starts. i wouldnt fuck with it in darkness tho imho
