Some people actually have read about 40 journals and have seen the results.
pH and o2 levels not consistent. I agree some folks are able to use this mixture.
I also found a trend in these journals and diaries. It seemed the closer to a 50-50 mix the worse it got. 80-20 and 20-80 seems to not matter as much.
As far as stuffing a bunch of perlite and vermiculite go right ahead. Very surprised you do not have cec issues which means prolly salt enviroment.
A lot of things that work for chemical nutrients will just not work in organic grows.
60 coco / 40 peat is the sweet spot. I don't build mine, I buy it and refresh, and it gets better. If you do drybacks it will punish you. If you try and irrigate like coco, it will punish you. One of its other strengths is it handles hybrid feeding very well so you can tighten up the ratio and fill any gaps you might encounter. If you don't know how to feed a plant outside your nutrient line or identify deficiencies, it's not your best choice. It's about tight control and being able to steer it, not a nanny grow. The key difference from DWC is you just aren't punished instantly. The downside is you can't quickly correct what you can't see is wrong right away. Better buffering than coco, not as much as soil, and just enough control to let you steer.
