Dear Growers

I have gotten two lab-results back from analysis. A and B below.

I need your help to calculate the PPMs for
Phosphor    
Potassium
Magnesium
Cobber
Manganesse
Calcium    
Bor    
Zink    
Iron
Sulphur

Looking forward to hear from you guys. Any help is much appreciated !

Best regard Peter from Denmark

Google cmol/kg to ppm. You have to know the atomic weight of mineral and then its a simple ratio between the two
