No I have not contacted them. I'm just leaving it at bad genetics. I've grown other things from them so I'm not bashing what they sell. Just bad luck. I've also tried to vegg 24 on and 18/4, and my room has zero light leaks. I've literally tried this strain 5 or 6 times from the same batch of seed. Maybe it's better now. If anyone has experience with this strain, please post.
