to put it back into veg would stress it a lot, and there would be a good chance of it going hermaphrodite on you. cloning a flowering plant works, though it has been a long time since i looked into cloning, but i always left my clones in a humid tuppaware in moist rockwool cubes with complete darkness for about a week till the leaves started to perk up a bit...be sure to use a good quality cloning horemone as well or you will most likely get nowhere.
