Week 3 Update
They are growing well and are showing preflowers. 2 have started to stretch and were ready to start some LST training. My typical strategy is to wait until they are 7 to 9 inches tall then bend/swing the main colas about 6 inches above the base to the rear or fronts of my tent in an effort to limit any potential light burn or stress as the get taller. I also reposition any smaller branches to give them as much light as possible and pull any large fan leaves to the sides and rear of the main cola.. I have learned to refrained from doing LST training too early to avoid damaging or interrupting the of the root crown or root mass. I'm beginning to see a few root tips showing out of the drain holes but continue to limit the amount of watering to every 3rd or 4th day as needed. Humidity is running between 60% to 65% most of the time. Trying to maintain about a 20 inch distance with my lights until some time in week 4. I would like some modest stretching but do not like my total plants height to exceed 30" if possible.
