Check your picture 1 just under your Cola you can see it there too, thin stem with a head on it. Take a close look they can be sneaky. I seeded one of my grows like this found the pollen fallen off on the leaves below the ball and had missed it. When I started looking closer I also found the odd banana hiding in buds, was pushing the amount of neuts the plant could handle. Maybe I'm the one being paranoid with your grow lol
