ATF and MTF are making a comeback in Cali, but I'm sure someone will just argue that it's not REAL ATF, etc. Etc.
But I have seen more clones out there from reputable clone vendors. I've grown and smoked an ATF cutting and it was great, my first real taste of high end weed that I grew. Everything before that was bag weed, so it's probably like how your first anything is always going to be the best. But I digress.
I've had several strains not change color, I've even took a strain way too long trying to wait it out when I first started. It's totally genetic like BT said.
