Just went through the same thing but mine was a hermaphrodite. My Purple Kush just went into 12/12 for the last two weeks now and all the fem seeds have held true.
Thanks for the offer CO, but I my camera don't really focus so well.
Now that I'm pretty clear what males look like, it should be easy enough to spot one if pops up again. I don't see anything closely resembling the pollen sacs on the other plants.
By they, CO, nice Youtube station...very informative.
