Are these flip to 12/12 clones showing sex yet?

I have regular 3 photo plants that I am cloning the tops in 12/12 light to reveal sex. Are they showing female sex yet? I don’t see any balls.

My guess is female.

I don't see anything to suggest sex, either way. But you should know soon, I see one plant has alternate leaves, meaning it's close to mature. I see something in the first pic too, but it's not clear enough to make out.
