What's on my leaves?

Question of a fellow grower:

I have some of your O.G. Kush Feminized in it’s 5th week of flower. I have just noticed that at the nodes [of the main branches I have a growth that is unfamiliar to me. There are small bulbs emerging there with a single hair coming out of the middle. I believe they are male organs and have started removing them. Do you think that this is correct. I have two of these plants and only one is showing these signs.

These are female, the hair is called a pistil, the bulb is called the calyx. These are called “pre-flowers”. If there was no hair, I’d be worried it is male.

Happy growing,
