Many great soils out there, kinda depends on your location. I'm on the west coast.
When I run soil, I have moved to nectar-for-the-gods #4. Well balanced, and every bag I've tested so far was on the money 6.5. It's not unusual to have drift during a grow, as the plant feeds on different things, but I had a bag of
test 5.8 at the start.
There are people out there that can do this without the meters, those are true farmers, they have a pH meter, it's built into their eye. Most do not have the eye, good meters and regular use is necessary to combat feed issues.
My guess would be, if you did a slurry test of the soil, your pH will be low, and your ppm high.
