Move your light closer 40'' away is to far. I would use a cfl for the first couple of weeks if I were you about 2/3'' away from plant and after it's a couple inches tall move it under your hps.

yeah slowly move it down move it to like 34 inches away wait two days then move it like -5 inches closer till you get it like 18-20 inches away just my opinion tho I only have one grow under my belt but thats how I have done the light adjusting and so far no over cooking!
