Hi Tom, great question, thing is that because you're on 12/12, pre-flowers are already showing, so the plant is starting to get stiff/hard already ! I cant choose for you to LST or not, but what I can say is that you should do it very soon otherwise the plant will be too stiff and the LST might negatively affect yield . Natural is nice, usually it works well and it's no trouble at all. LST is a longterm engagement, you have to fix it up every few days and follow the plant, but it can really help on the final yield. Hope this helps ! ๐
