1st...quit worrying about the light. That light is great for 1st timers. I have a 400w MH on my youngun's...As long as it is not too close. With a 400w...You don't have to be right on top of them...
Just think???what did people do a few years ago before cfl's? they used MH or fluoro tubes.
The whole deal about the light MH or hps -vs- fluoro for seedlings.
Fluoros allow the seedlings to grow more roots before growing up, because the light isn't intense. Anyway. forget about what everyone says, and grow a grow.

They are too young for nutes. Let them root good 1st and get 4-5 alternating nodes. All the young ones yellow a bit...Do you have the water level just below the bottom of netpot? You do not want the water level up into the pot...hope this helps...peace L

Go to amazon and buy Indoor marijuana cultivation "the indoor bible" by J. Cervantes. I got one for $10 bucks. It basically tells you everything you need to know, and is a great reference. I'm not saying that I mind helping, but you would benefit greatly, buying a grow book.
