Its a nutrient, its good to test if your p and n are on the low side. Not really much data on potassium but some including myself will test for it. Guiesman acually just came out with a line of test kits including potassium that i want to try. The other standard would be salifertI have read that Potassium can do a lot for certain colors...I think I'll track down a supplement and test kit for this and maybe Potassium iodide. I know it is in one of the additives I have been using in at least small amounts, but it's never a bad time to step my game up.
