Good move on the transplant. I really underestimated my roots on the first grow and had to transplants 3 times. My plants were mad.

A couple suggestions though.

First Use Mylar. You can get it at your local indoor lighting/grow shop or order it off the internet. 15-20 bucks will get you all you need.

Second your probably need more lights. I didn't catch how many plants you said you had but you probably need more. More is always better. Look for the larger full spectrum CFL's. They usually are 55w or above and usually run about 25 dollars a piece. You can order them off 1000bulbs.com if you cant find them locally.

My last suggestion is that you top your plant(s). Doing this will transform your single stemed plant into a 2+ stemed plants thus producing more area for beautiful buds to grow. You do this by cutting off the top sprout right above the highest node. You will need to do some research on your own but you will probably want to use the FIM method (Fuck I Missed.) Check it out, it will greatly benifit you.

Top them, give them a few weeks to make sure they have recovered then switch them into flowering. Another trick is to focus your light on the sides of your plants leaving no direct light above your plants. This will encourage them to grow up more instead of out.

Good luck bro.
