This plant has never looked quite right and I just noticed its pistils have a bit of a "bell pepper" look going to them. It's a feminized auto flower and it's looked unhealthy as long as it's been alive.
What does it look like, normal pistils, hermaphrodite, or just something to keep an eye on?
If your plant is going to herm out it will happen later in flower. Usually when the bud is ripening; or at least that's how it always was in my experience with girlie-boys.
