I have two cannabis seedlings that are the same age. If I rub my fingers on their stems and smell my fingers one of the plants smells sweet and delicious like candy and the other one smells more earthy. Is the sweet smelling one more likely to be female. I will check preflowers when the show. Cheers
While many will say smell plays into the sex i think if you have a seedling still its nothing you need to be worrying about at this point.
