thanks alot yarddog, i appreciate all u guys stoppin by to check up on me, well it's 1221 am est, and the girls are doing ok, one of them already have a tap root shooting out the bottom of the cup, and it's like an inch long!! i'm thinking about adding that extra 42 watt 6500k into the mix to see if I can get the ones in the back to get a little bit more vertical growth, what do u think? still some yellow in the leaves, but thier partially green as well, so i'm guessing it's nothing to worry about, adjusted the ph from 6.1 to 5.7 water temp is 70F, and air temp is 73F
