I can’t tell since it was pulled off but if it does get pollinated you will notice the pistol hairs will go from white or orange to brown once seeds are inside! It’s possible it was 1 but hard to tell but keep an eye on it! If it was and was only 1 could be from stress but plucking it will keep it from getting worse!
Hey Growmie,
This is like the ovary of the plant. If the plant get pollinated by a male plant this turns into a seed. At this moment it's not a seed. So no this is still a female plant. Hopefully I answered your question and remember Happy Growing and Free your mind one puff at a time.
