New ones wont appear to take the place of the old ones you pick off, but new ones may come out in other areas, maybe, so just examine every day. Also, wipe down the pots as well. Remember you can transfer the polin from one plant to another with your hands, so take care not to.
How long of flowering time does the strain have? If only a week or so more, I would think about getting ready to cut. If the others were polanated you may be able to cut them before seeds do develop, just a thought.
