Hey bro nice choice of strains. What I did was switch from my 600watt MH to 1000watt HPS when I switched nutrients to bloom nutrients about 10-15 days after they showed sex. That was something I discussed with Muddy who knows his stuff. You should check out his Life cycle of a autoflower thread. Lots of good info in there....
Good luck with your grow, lots of green karma your way.....
