understanding the way plants uptake and use nutrients is alot more than simple ratio math. and proper diagnoses is more than just identifying what nutrient might be the problem, you must figure out why it is a problem and how to make it better, and that does not always involve tweaking your nutrient ratios. There are alot of other factors which affect uptake.

Ca and mg increase with rising ph and k uptake decreases.
no... from 6 to 6.5 K remains fairly consistant... why do you like to argue so much?

Because sproutco/bv is hellbent on trying to prove he can be an authority on growing marijuana using theory and formulae without any labwork in the field.

The only way hes attempted to accomplish that goal is by telling veteran growers with years of labwork in the field how wrong they are without offering much evidence.
