Smelling the sex?

I know trying to guess at the sex of a plant before it shows is silly but I've got three plants 2 afghani#1 and 1 Chronice ryder (fem) and of the afghani's one is WAY taller even though theyre only about 1 and 1/2 weeks old one is nearly seven inches tall and the other is about 3 and 1/2. (the ryders about seven inches too but I'm fairly confident its a girl) I know height is a fairly reliable early method of telling the sex of the plant does that mean the bigh afghanis a guy?

as a note the bigger afghani smells to HIGH HEAVEN compared to either of the other two plants (nice and lemon zesty in a mary jane kinda way) should this be take as a sign the plant is a girl?

odor isnt a good sign of sex, the only way to tell is pre flowers or when it shows

ime my males usually have a pungent smell on the stems, and when combined with the taller structure it never fails I don't have to see the pre-flowers (although I always let them go) Above poster is correct that it isn't a good indicator in and of itself.

if it smells like my ex (fishy trashy whoreish) it is a female.

lol okay I was hoping the smell meant it couldnt be a boy. I'll just wait for the preflowers to be sure I could just have a tall pheno *fingers crossed*
