100% definitely male flowers.
I can't see any pistils to indicate that it has any female flowers, so it could be a pure male plant.
Once a plant flowers like this, it will continue to produce male flowers continuously, making it a poor choice to keep it growing any longer.
If this was grown from a "bag seed", this demonstrates why doing so is a huge risk and it is far better to spend the money and get quality feminised seeds.
Hope this helps,.........
