Put em under your LED asap. Then let em go nuts. The more light, the bigger and badder they will get. Don't leave em outside much, unless you want to possibly deal with pests. I wouldn't worry about LST'n until you can grow some dank, then you can figure out increasing yield and all that fancy stuff. Keep it simple for now if you notice who grows the dank on this forum, it's without LST or complicated nutes schedules. Letting nature do its thang. But that's just one stoners opinion.
