working out your ppm

[plantnoob]

im using the ei starter kit from APF . i mix my bottles up slightly stronger than the guidelines ( 1tsp more of each powder) . i was curious about what sort of ppm im getting in the tank . is there a formula to work out the ppm of each powder in the 500ml dosing bottle , and from that a way of working out the ppm each dose puts in the tank ?

plants are not showing any signs of defficiency , i just want to feed my curiosity

PPM = mg of powder / liters of water in tank.

Cheers,
