I finally got my fert from GLA. I got the complete package. According to the EI dosing regiment, it does not say how potassium one should use. I assume potassium is added when dosing Potassium Nitrate. I have a bag of Potassium Sulfate. How much should I add?

you should not need any if following EI

Potassium is the "K" in NPK. True, when you dose "N" and "P", you are adding potassium too. Some folks don't add any more potassium other than with N & P; some folks add it via Potassium Sulfate (K2SO4).

If you scroll down to the end of the first post, there is a visual that includes K2SO4 in dosing regimes.

Thanks. I think I would dose some since my Temple Plants are always hogging all the potassium. I still have some leaves showing signs of potassium deficiency despite that I have double my root tab applications. Double does my liquid fert, which is Tetra FloraPride (it has only Iron and Potassium). I am not planning to dose phosphate since my phosphate level is consistently at 5 ppm.
