Just curious - ever try FFOF only in one pot as a baseline for how their mix performs?
Asking since I'm running 7 with FFOF only - mostly because I'm new and want to stay as simple as possible moving forward.
I don't mind the idea of adding nutes on the next run, or maybe to a select few if I have problems this time, but I figure that I'll never know what effect nutes are having unless I know how well the base soil performs.
I tend to be a bit KISS obsessive in practice - but in my brain and on paper there's a madman trying desperately to explain himself...
