You are going to have a tough time LSTing those tightly noded plants. I would start now by spreading out the secondary branches as much as you can by anchoring them to the outer rim of the pot with plastic coated wire. Very squat, but very healthy looking!! Do your lights have IR spectrum in them? It seems to me that they might be a bit close and are causing nodes to stack, but I don't have a 900w. Is it 3 or 5w diodes? Next round I would consider filling the pots with more dirt, I like to start with them levelled off and then once you start watering it will sink down to around an inch max from the top.
