Oh wow. Thank you for doing the research. That's like 6 years ago. Maybe they crossed with new stable strain recently. I read some Blue Mystic grow journals and seems like they are okay. Some people just have troubles with their grow techniques.
Oh and I like how they give out 10 seeds for free on every order because I like to see them grow mysteriously. Good for breeding experience and skills.
When you grow a few plants of the same strain at once and you get 3 different phenotypes that's not bad grow technique that's called poor genetics!
