Yea, soils can regionally vary.
it sounds like you got a good system going. I wish you all the luck.
I used to run no till in an earthbox, with bas 3.0, craft blend, cowoco ewc, build a flower, build a bloom, etc. After harvest i would grow a cover crop, like this....

Then chop and drop.

Then reamend, let sit for a couple weeks, then repeat.
My issue was, buying all the different amendments.
Nowadays, I'm using ffhf for a base. I top dress with ffof thru veg, then in flower i top dress with flower girl and ffof, and use recharge once a week. It's been working pretty well for me, it's been easier, and a lot cheaper. Lol
I've learned with fox farm soils, if you keep the microbial life thriving, it does pretty good.
Another guy on here does something similar, except he does a base layer of ffof and the rest ffhf. It seems to work pretty well for him also, but I'm not sure where his soil is sourced from.
