Random Seed, looks like an auto

Got a random seed as a freebie and it looks like an auto. Started flowering under 24hr light in my veg area. Never grown auto's, but it obviously is one as it is flowering 4 weeks out from seed. What will work out better if i leave it under 24 hr florescent light or if i move it into my flowering tent with my HPS on 12/12? Or should i just keep it under the fluorescent for most the time and under the HPS when i can?

If you can, put it under the hps for 12 hrs then move it to the flos the other 12. That's what I would do.
