Hi
@paparazzi! Avoid any kind of stress after the 2nd week of flowering, you don't want the plant to drive its energy into recovering, you want her to give everything she got into bud fattening & resin production. Indeed your plant looks small, but at this stage there's not much you can do, LST (or any other technique) won't help you to get more nodes, this should have been done earlier. Hope that makes sense, keep us up-to-date and happy growing 👊
