How to calculate the ph of a solution
WebAcceptable pH Range for Coco: 5.5-6.5. Coco does not buffer the pH of nutrient solution as effectively as soil and therefore it is critical to set the pH of the nutrient solution inflow within the range of 5.5 to 6.5. Because different nutrients are soluble at different pH, it is best to allow the pH to drift up and down within the range on ...
