hey there again statman, congrats on the first growbox, it is a lot of fun but sometimes it feels like a sport, if you know what i mean? Anyway to answer your question : start as early as possible, for example now is a good time to start. For autos you do want to start early . that's because autos have a lifecycle where the stems and stalks start getting stiff/hard around week 3/4 so it becomes difficult or impossible to do LST after a while. Also if you start LST too late on the auto it can lead to loss of yield because the flower nodes dont develop correctly. So LST is used for two things : increase yield and manage height. It increases the yield by encouraging lateral growth. So what you want to do is create a lever or an anchor by supporting the base with a hook then bending the plant over the hook using ties. So tie the plant in two places : 1. at the bottom to create a little base/height at the bottom, and 2. bend the top down and tie it to the pot. Based on your video, you did a perfect job ! Dont forget to follow the growth of the plant and make adjustments ! Hope this helps !
