Ive never done this. So my advice is based on similar but different circumstances.
In my case I had a skunk 1 growing indoors. When she was in week 4 of flower. Brealized she was last of her kind so I pulled clones while in fliwer and reveg. Took foooooooorrrrrrever. Like 2.5 months to show ne growth. So it may stunt them pretty good if you try it.
