I checked a fresh bag not too long ago I forget exactly what it was I think it was maybe 700 PPM and 6.3 - 5 it was in the zone
Variation has to do with how and how long it's been stored. I had a bag that have been sitting around a local Hydro Store recently and it was kind of wet & nasty and it was maybe 17-1800 ppm & pH was quite low too so yeah, agree and you got to do a slurry test or you're just chasing demons

amended soil isnt an inert medium like rockwool, coco, peat. Measuring the runoff you arent sure when you see 1300 ppm and a ph of 4.6 that that is actually what is in the root zone or the runoff from the amendments ect. Slurry test will give you a better reading in a situation like this. Testing runoff really isnt a great method anyways. It will give you an idea and can steer you in a direction but what is happening around the root zone and what is coming out of the medium is usually 2 different things. A lot of that is affected by moisture.
