RQS Milky Way F1 - Auto (70x140)

Started LST on the right two plants (#1 and #2) - leaving the left one (#3) alone but doing some heavy tucking of the fan leaves. I am watering to runoff about once or twice a week, and the runoff EC and PH are looking OK (slightly higher EC than whats going in, PH is around 6.8) I am liking how #3 responded to leaf tucking, side branches are as tall as the main branch, similar results with the other two who receives LST. Having issues keeping humidity below 60%, may need to get a de-humidifier once flowering starts.
