Er, you need to pick out the males quick (at nine weeks, they should be showing sex). Check this out. Should help you distinguish them apart. If you don't pick out the males, you'll be lucky if you even end up with mid, much less than dank. But you'll have plenty of seeds for next year!

And as far as ending up with dank goes, genetics does play a factor. If you're growing some sort of skunk, no matter how well you take care of it, you're not getting White Rhino.

But you sound like you're doing a good job. You should end up with some decent mid if you get the guys out of there.
