Well, let me correct something before I get called-out on it. The stigma's are the actual tubes, (white hairs) the pistil is the reproductive package that delivers the pollen to the ovaries. When they appear is usually different for each strain. Usually within the first 5-6 weeks of growth phase.

But just because they appear in the growth phase, does not mean you HAVE to flower her soon. It means she's ready to flower when you are.

For pictures...turn off the fans, raise the lights a bit, and steady the camera on books or boxes or something to keep the camera steady. Adjust the white balance if you know how.
