Looking good bro, looked at your last picture, with the CO2 tubes and the three together. What kinda height is the largest on the right at now.....i only have 1 and my largest is peaking around 14" trained pretty hardcore.
ALL of the leaves seem very thin and light green, not sure if thats normal or not, as mine were all dark dark green, but mabey try to get the lights closer as well, i think that may be a sign of having enough light, but wanting bunches more.
You live in the southeast, i do as well, temps today inside in the apt today were reading 82F, the box was reading 87 at one point,. Outside temp today peaked at 79F. If you can get your house or apt cooler, that would help, bill will be slightly higher. But unless there at a constant 90+F daily then there growth will slow above 90 and above almost come to a stop at 95F, at 100F for long time periods will kill them. If your working with outside temps it'll be fine, but if its inside of something then it'll be alot more abrupt, ease it into the temps, don't shock it.
