Hey man ,I had the exact same setup at the beginning of my current grow (exactly the same, including nutes and strain). I'm still using the 3 part AN on my grow but I picked up a 400 watt HPS during veg and started using it with the cfl's. I topped and LST'd the hell out of mine. Check my grow out if you want, I'm on day 12 of flower and it's my first ever indoor grow. Good luck!
