Nutrients ppm

[iknowkungfu]

Hello!
I Looked in the forum history and didn't found answer to my question.

I want to know how many ppm the plant needs from each mineral in each growing phase to build a fertilizing plan.

Im using soluble chemical fertilizers such as
Potassium nitrate
Magnesium nitrate
Calcium nitrate
Mono potassium phosphate
And base fertilizer 4/2.5/6 with 12% micronutrients

Where can i get that information? Studies?
Thank you!
