First Grow w/ T5's and 700w LED

Week #2 / Day 8 of the Green Crack. I have been able to keep temperature and relative humidity fairly consistent between 65F (nighttime low) - 84F (daytime high) and a relative humidity between 30%-65%. I would say my average temp/rh is around 77F/45%. I plan on keeping this girl (wishful thinking) in an 18oz solo cup until the leaves start to overlap the diameter of the cup. I have been watering every few days with room temperature de-chlorinated and filtered water with a ph around 7.
