Anything that's putting its energy towards growing seeds is going to be less potent. Hermaphrodism can be stopped, people use something from Dutch Masters called Reverse (in conjunction with another product called Penetrator) to stop seed formation. If you ever get buds filled with little malformed seeds, it may be bud that was hit with this stuff. I'll try to get a close-up of a fat calyx for you, my girls are getting a lot of them (and, I had a plant herm out on me during the ONE week I was out of town). I've already found some seeds in the quick-dried buds, too.
