Sexing question

I've got five plants outside there all doing good but one of my plants already showing it's sex while the others aren't why is this?

seeds genetics? are they all bagseeds?

Yeah they are bag seeds I'm surprised they even sprouted I just checked on them the other to find out they actually grew they stretched a lot but since I know that they are there I'll take better care of them

You can never expect all your plants to start sexing at the same time. Some plants just take a little longer, its not a bad thing.
