From the looks of it, it is heat stress. What kind of light are you using and how close to the plant is it?

It's on the lower leaves though so it might be too much nitrogen.

What color light are u using? Try a full spectrum CFL or a "Bright White" those "soft or warm" white CFL's are no good for vegging and they get hot too... Do you have a fan? I agree... It looks heat stressed to me. Check the PH and temp and Humidity also.
