Yes 12 hours a day of your lights is definitely contributing to algae growth.

I turn on the blue actinics and then an hour later the white. 8 hours later I turn off the white and then turn off the actinic an hour after that.

The green star polyps will spread don't worry. given time and good conditions they will spread and fill in nicely.

COOL so now im just gonna leave the light on for 8 hours see the diff
 
I run the daylights / white lights for 7 - 8 hours, too. I run my actinics / blue lights a little longer, having them come on 90 minutes prior and turning off 90 minutes after the daylights.

And yes, your green star polyps should grow and spread nicely. Perhaps too well, in all honestly, but they are easy to frag when needed.
