Looking forward to seeing what you do with the MAC.
I don't get to sample much that I didn't grow myself and MAC is one of those strains that I had opportunity to sample when visiting relatives in Florida. Loved it.
Several other strains were tried, and didn't measure up to my own.
You may not remember,
but last year when I was growing Hawaii Maui Waui, I had an issue with a Calcium deficiency. You mentioned it, and I couldn't see how that was possible as I was giving them plenty.
Well it turns out that I was running the PH too low and letting it get really low at times.
I'm almost certain, that was causing the issue with Calcium uptake.
Good call
