wondering if my plants are suffering

Im relatively inexperienced with hydro, trying out a 16 site ebb n gro system i built. Can anyone tell me if my plants are lagging behind? They are two weeks from seed .

I had two 600w but ran too hot and now down to one. Worried the temp spike slowed em down. Thank you!
 
hard to tell with the light on them. they do look a bit on the light green side and if so you may need to up the PPM of your nute solution. at this stage i would say around 400-600 ppm should be fine.
 
get a pic up without the light so can judge how green they are. a light green means deficient and dark green means over fed, i dont think they are dark green but its hard to tell if they are too light or not with the light on for pics
 
Changed to mH bulb, cant get good pic with lights off. Question, can i start some kind of fim defoliage regemine this early?
