growing to tall problem

I will post pics later as I cant get into the cabinet due to the lights begin off.

My delima is that my cabinet is about 6' tall but with the light and exhaust i might have 41/2 to 5' max my plant can grow.
I just put it into flower 2 days ago at 4 weeks old and its hitting the 2.5' to3' mark now.
I assume it will at least double in size if not more during flowering so if that happens what do I do or what can I do now to help fix this issue.

thanks
here is one pic but its about 4 days old so its much taller now.

there are some nutes that stunt growth...Bushmaster by humboldt county's own, and phosphoload. both nutes stop all vertical growth, just be careful to not add too much cause they are potent!!

or you can try bending and tieing the coloas

yah, i was going to say that you can either do some supercropping or you can start to tie some branches down.. i'm a fan of supercropping personally..

You are welcome.
