It would not kill the plant, but it would deff stress the plant alot. This would slow down all the production of the other bud sites, and focus most of its energy on the wound. and takes a bit of time to fix the wound and regrow, and if you did this during flower you wouldnt have enough time for it to regrow and start to produce bud.
