First Grow: Health?

I just started growing recently and has been about 2.5 half weeks already into vegetative growth.

my setup:
computer case
4 6500k cfls
1 intake
1 exaust

plants:
2 northernlights

humidity:
40%
temperature:
80*f


I have noticed some spots on the plants and not sure what they were. is this bad?

They look great. Sounds like you might be getting mites. Get some spray and kill them fuckers be they really get out of control

They look fine, but you're gonna need a whole lot more than those 4 CFL's if you are going to want to get any more than a 1/4 ounce
