if you're going to re-veg, only do it to take clones. I should have taken the advice of others when I re-vegged some plants...I'm actually finishing up with them here in the next couple of weeks and I'm kind of disappointed. I did it because I didn't have any good seeds, now I wish that I had ordered seeds and just waited to start a new grow. It will also take a while for it to revert back to the veg stage. You will notice new growth within a week or so, but after that it takes a few weeks for it to be truly vegetating. This is from my experience, so I can't say for sure what will happen with your plants.
