How big is your space? Three may be extreme, but I live by the philosophy, if you can control the heat, the more light the better. Keep 'em a bit higher at first and lower them as you see fit.

My space is about 12 by 12 foot goin into an apex at the top i have all three lights running through a 6 inch ducting all three are cooltubes will i be alrite just switching all three on tommorow? And do you think its going to still be to much heat?

I use cool tubes and they work marvelously. My 40x40x78" tent stays in the 70s, with a 600 HPS. I think you'll do great. Go ahead and switch, if you must. Remember, plants stretch 2 to 3 times their height once you flower. After 3 weeks, do you have enough growth to fill your space? If so, have at it. 600s will throw pretty deep through cover, so make sure they will maximize the space, without outgrowing the light, since they'll not produce too far below that lighted area.
The light won't burn them, the heat will. If your airflow is adequate, I don't think you'll be unhappy with your results. I would not be surprised to see 1500 grams. Maybe much more. Good luck. Let us know how it goes.
