You still have a little while to go.
Some pistils are going brown, but there are still a lot of white ones and your flower is still bulking up.
Normally flower is 8 to 10 weeks and outdoor normally on the longer side. You have at least 3, probably 4 weeks to go.
It's like looking at a tiny green orange and wanting to pick.
Generally, if the plant isn't foxtailing, you want to wait until 90 to 100% of the pistils are brown.
