Leave the plant to flower. Those seeds will be useful in your next harvest. Also, seed production, contrary to popular belief, does not impare quality greatly but only quantity. The female will put most of its energy into producing seeds so you will not have as much smokeable material but it should still be of good quality. I suggest you harvest some of the buds at peak maturity and let your lower seeded buds stay on the plant for the seeds to mature. Hope I was some help. Out of curiosity, what strain are you growing are is it just bag seed?
