Hey fellow socal grower, looks good so far. I'm hoping to start a CFL closet grow soon, so I'll follow your progress. Not sure what the yellowing is about - is it possible the nutes were given too early? I think most CFL growers will tell you that you can get results with the lights you're using, but more is almost always better. I'm assuming you're going to add more as they grow. So far, I've purchased (3) 68watt CFL's and I only plan on growing 2 plants max. I will probably have to get more to ensure a good crop from 2 plants. Cheers.
