Hi fluorogrw, welcome! Your plants seem pretty healthy but be careful with the nutes. They look a little young to be giving them much nutrients already.

I also used miracle gro for my veg nutes. The plants seemed to like it. I just fed them at 1/4 and 1/2 strength until I switched the lights to 12/12.

If you're looking for cheap lighting, try CFL's. A lot of people around here have good results with them. Myself included

Keep us posted!
