Would you mind giving me some specific Links regarding P and Ca beeing the important Macros for Quality?
There is this Idea that the Plant doesnt need Ca in later Stages, thats why Growers cut out Calcinit later on. Whats your Take on that`?
Here you will find a lot of good reading. Read the Elemental Uptake article and then look at the PDF with the base calculations and the "grading" of the actives against the calculated (my math) base distributions. The data set came from the article and you can see there is an active ingredient quantification. Note the leaf analysis and the soil analysis against actives, might give you a bit different perspective. Note what drives actives, sure as hell isn't K nor Mg! LMAO
And if want to read a good book, there is the Tiedjens book to read.
