It doesn’t make much difference overall, but it helps paint a clearer picture against your Jacks 321 numbers. The nitrate to ammonium ratio doesn’t change that it’s heavy on P and really light on other things like S & pretty much all the other micronutrients as you mentioned.
Feels like they assume the use of a bagged soil where micronutrients are coming from other sources, even though they advertise it for any growing style (hydro & soilless inclusive). And now that I’m re-reading that, they always mention Fox Farms Ocean Forest as a recommendation…so they might be working with that as a baseline. Hmmm.
