sexing by color of leaves?

[MrLzyBones]

I've got 3 somango's growing outside.2 are a slight darker green than the other 1.Also,the 2 darker ones already smell quite skunky and there still just plantlets.The other lime green 1 bearly smells.In comparison it's nothing!
Anybody ever heard this before or experienced this?
Because I'm willing to bet the skunky ones are the girls but I don't really know.

I don't think i ever heard anywhere you could tell by this. Whats happening is that you have the same kind of plant but different traits are coming out in them. Untill its a stable strain but there is always the chance the same strain being slightly different.
