That is what I was referring to with trying to use EC readings with the two nutrientsEc readings in a partly.or mostly organic base is near impossible first off. This was one of the early problems with the original Pure Blend Nutrient back in the nineties during testing in greenhouses (Growers Edge Sept 1997). And yes they are totally different in make up. But the end results are nearly identical if you have a consistent amd controllable growroom no matter what the climate and weather conditions are outside.
