Demontrich is on the money. Just did this myself. although depending on the straing, etc., It could take longer than two weeks for normal growth to resume... Take clones as usual, but be prepared for some goofy ass looking growth at first. The plant's gonna be confused and may throw out some single finger leaves, Leaves without serrations, twisted and contorted leaves, and maybe some other straight up strangeness. But sooner or later the plant will get the message your trying to send, and it'll go back to veg like a good little girl.
