Knowing that P is about 43.6% pure and K is about 83% pure.
If I take Potassium Phosphate for example, which is approx P-52 and K-34.
Do I measure using 52-34 or do I measure using the actual 43.6 and 83% of 52-34 ?

If your trying to calculate PPM you would have to x by .436 or by .83 first.
Eg. 1 gram of MKP would give you .226g of P
and .282g of K
Or 1g in 1L of H20 would give you 226 ppm of P and 282ppm of K. That’s if my math is correct.LOL
