I have never grown an auto flowering plant, I would keep it on 18/6 or 20/4 (im not a fan of 24/0 as I think plants need a rest) and she should start to flowering soon. Yes I use a HPS for flowering, but you can use CFL's in the 2700k light spectrum and should see some good results. Good luck and keep use posted
