Any luck with high CBD strains?

I'm stumped by this one.

Growing ACDC high CBD strain and cannot seem to get it going. I've heard it's a difficult strain to grow but thought I'd give it a go anyway as I have more than a dozen successful grows under my belt.

Looks like a calcium deficiency so bumped up cal mag and no change... spotting continues to progress.

Any other thoughts?
Anyone had success with this strain?

I'd say it's your environment, I've grown it many times and no issues at all

Looks like you have root issues or a lockout in your reservoir. I'd change the reservoir water and add low strength nutrient solution.

This was one of the main buds from my just harvested cbd grows. She grew some very big and fat colas. This was a fastbuds cbd 20:1 strain. Less that .03% thc and averaging 15% CBS. I use it for tinctures and making cbd pills with coconut oil.

Thanks for the feedback. Maybe it is lock out, I'd be so surprised since my nutes are 1/4 of the recommended and I have another strain in the same reservoir that's thriving. But that's how these things sometimes go.

I'll change out the water and will update.
