you can transplant anytime you want, if done correctly, it will slow down the plant's growth for a few day, then start right back up, as the roots grow out (back off on your lighting for the first couple days, it helps the rooting) ... and, don't fertilize around the transplant period ... personally, I would transplant ... whatever you lose in the stall, will more than be made up for, in a larger, healthier plant ... it's your plant, do as you like ... :smokin:
