Magnesium helps unlock soil phosphorous, according to the Mulders diagram. Some sort of nutrient interaction. I know nothing about feeding phosphorous other than bone meal and bloom booster seem to work.

Maybe you already understand (and cant fix) the uptake of phosphorous. That being said this chart is interesting, (if redundant, perhaps this is old news to you.) Temps and microbiology surely play a role. Sorry if I'm not answering your original question.

Its a good question.
