more nodes... LST is to spread growth evenly among axillary branching... if you want 3-4 primaries, now is a good time, but not likely. Also, if any originate at or below teh bend , those are lost branches.. should cut them off. even if you do extreme training to keep them level, they will be visibly lesser colas. So, you may lose a couple branches when you do LST.
plus, how big is that tent? 6 plants may not need lst if you are in a 3x3 or 2x4. you want a short vege and will have a sea of green type situation.
