How can you measure potassium in ppm.? Is there such a thing as a test kit that will measure potassium? I have not found one. How do we know there is enough potassium in our dosing?

You can get potassium test kits, however the accuracy has to be questioned.

I just watch the plants growth, if i see K defficiencies (pinhole/ burnt holes in the leaves) then I dose more
