Mixed auto and photoperiods

I have 7 plants crammed in a small tent ( balls'ed up) under 2 x 200 CFL's and 2 x 48 grow tubes. My question is they are all about 12-14 inches high and the auto have signs of flowering, do I put the tent on 12/12 for the non autos? Will this hurt the auto as I'm told they benefit from 18/6?

Driving me mad.

Thanks

well i know everyone says 18-6 ,24 on or what ever but i have one in my flower room that started outside and when it started flowering i pput it in my flowering tent and still going full flower.. looks like a soda can on a stick..

Cheers, going to go to 12/12 tomoz and see how it goes
