We'll the lower half of the plant looks more even, the top is more complex and their are ball like things on the internodes.
I don't see any balls... the first pic is just your nodes swelling to make the stem stronger so it can support the buds I don't see a sign of sex on that node. The seconds picture looks like a female, I don't see any balls mixed in with it..
There are ZERO male flowers in those pictures. The little lumps at the nodes are just the knuckle between the branche and main stem.
