Agreed. Too many variables to consider when understanding nutrient uptake ranges and ph. It’s best to swing it from 5.5ish-6.5ish to mitigate deficiencies but then that brings in a whole new set of problems. There are auto ph brands, but that’s something I have issues with. The charts we all go by to understand it contradicts what they offer. No one ph level is perfect for a plant, it needs a combination… Maybe I’m wrong but until that is fully understood and solved, organics will be superior. We just don’t know enough in my honest opinion. I chased deficiencies left and right during my DWC days.
