I dont have MH`s like you do but I have VHO set up. I have my actinics come on at 10A and then my 50/50 (white lights) come on at 11A. The 50/50`s go off at 9P and then the actinics go off at 10P. That`s just my cycle. I try to have the actinics on first and off last.

12 hres may be a bit much for MH's. Are you up that early in the day...6am. you might want to start the light cycle a little later in the day,, say 9am or 10am, run the MH from 10 or 11am to 5 or 6pm and then the T5's finish off till 8pm-10pm depending on when you go to bed. That way you can enjoy viewing your fishtank.
Happy Reefing,
