Pistils are funny things and there are several reasons that they could be turning orange this early.
- They've been touched or bumped. I've had pistils turn orange just from my sleeve brushing against them while tending to them. On my first grow ever, I was like a curious child and I couldn't resist touching them to see what they were like. Literally the next day, that bud had orange pistils.
- They also start turning orange if they've been pollinated and that usually happens from the tip of the pistil downward. From your pics, this is sort of what looks like what might be happening to yours, but can't be sure. Triple-check to make sure there are no males or herms in your garden. Look very closely for nanners as those can be hard to see but at this early-ish stage of flower could end up causing a very seedy harvest.
- Sometimes that's just what the plant does. Different strains, different genetics, etc. all affect how the pistils behave.
Overall, if your plant is looking healthy and behaving as expected other than the pistils, just enjoy the color and being part of such an amazing plant! You'll probably see new pistils growing as the flowering phase goes on. This makes sense as the purpose of the pistil is to catch pollen so if something happens to the pistil (gets old, gets touched/bumped) that prevents it from being able to catch pollen, the plant lets it die and grows more. The more you grow, the more you'll see just how brilliant plants are! The more you grow, the more you know!
