Thank you for the advise on the pots, Weedhound.

Do you think that the amount of space for the roots is what is causing the issues with my lower leaves? Do you believe that is the only issue based on the information I have provided? Other than changing the pots what advise would you have for me at this state?

Plants are now between 10 and 12 inches tall (From top of soil) is this a good time to kill the lights for a day and force them to show their sex? What height/characteristics should I look for to know when to switch to my HPS set up?

I'm currently studying to be an electrical engineer so burning down the house by using the wrong wiring/lights/ballasts is not a concern of mine.
