Also, especially on that first picture, the whitish stuff to the back looks kinda like white powdery mildew, to me. Can you wipe it off? Hear is another link about that, for you to check out, so that those beautiful buds don't get ruined by that stuff!
The plant will only make pistils once, except when it is getting stressed out by heat or something, also, they can continue to make pistils sometimes late in flowering as well, in an attempt to get pollinated, but that plant looks like it is just doing normal stuff, and needs a few more weeks till harvest, and maybe some WPM wiped off. If you have problems with mildew, there is a way to wash the stuff off at harvest, as well, had to do that to mine this fall.
