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?

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).

Check out this sticky for all the goodies regarding dosing: http://www.plantedtank.net/forums/fertilizers-water-parameters/21944-_dosing-regimes_.html

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.
