Bushies under lights

I've got bushies under lights, which are powering and a week into flowering.
They are not really showing any sex, and I have heard that bushies will continue to grow under lights and not flower, is this true?
If so what is the solution?

What exactly do you mean by "bushies" ?

introduce a 24-36 dark period to get the flurol(?)(the chemical that appears when 12/12 is introduced) flowing real well and to let the plant know it's time. Right now I am growing a strain that will not flower without a 24hour minimum dark period. I even tried superbud once and it was 2 weeks on 12/12 without flowering because I didn't use a 24-36 hour dark period first. Sometimes it's neccessary to get tough and tell the plant what to do instead of the other way around. Good luck.
