is that a soil or hydro grow? if its hydro your ph is off, and 600ppm could maybe be a little nute burn. try to bring it down to 400 ppm.
 
What sort of nutrients are you using? What stage is that plant in? Are you lights air cooled? What sort of lights are you using?
 
im useing IONIC Grow Solution its for hydro but the guy told me u can use it for earth and its just as good the plants are about a mounth and a half old thay have 2 - 1000hps on a rail and two fans blowing between the lights and the plants
