How come one of my plants smells

but the others don't? They are really small right now. None are taller than 7 inches. And the leaves on the one that smells are probably half as big as the others. It's weird. What does this boil down to? Strain, sex, nutrients, does it just have more healthy genettics?

It smells like skunk. I am going to go sniff it right now.

I have the same situation with 2 plants. Does the "smelly" look slightly different from the rest? My "smelly" is somehow lighter in color than the other plant and has leaves much wider and branches much shorter than the "non-smelly".

the amount of smell different from strain to strain....some will have just a mild odor..while some just stink....

it pretty much all differs from strain to strain

It is all DNA...no affect on sex, or anything else.
