Unfortunately THC doesn't agree with me so I've been growing Sour Tsunami from clone. I was considering growing Joanne's CBD by RQS and I was wondering if anyone had any insight into how much variation of THC levels there would be between phenotypes in strains with (supposedly) trace concentrations of THC

Harlequin was one of the original ones I believe, but Sour Tsunami has been around for a while too. I first grew it in 2015 and the clone is still floating around. What I'm really curious about is how much the THC levels would vary between phenos when growing CBD strains from seed. I use CBD for medical purposes. I love growing weed but THC isn't for me sadly

should all be relatively the same if coming from breeders,
landrace heirloom etc would have differences to varying degrees,.

Cool. I might give it a shot with Joanne's CBD. Supposedly a decent yielder and a short flower for a Sativa dominant strain and the RQS website said it keeps you clear headed and calm. That's what I like about the Sour Tsunami, but it's the only CBD clone I have access to and it gets boring always growing the same plant
