Maybe I'm not making myself clear enough here. Sorry,
What I am talking about is making the A&B solution up, then taking it through a pH range to ensure all elements are dissolved before bringing it to a stable pH of about 5.6-5.8 instead of keeping pH more stable throughout the mixing.
I guess I am saying that by taking the nutrient through the maximum pH range during mixing (and while in the res, not pumped through the substrate), surely we can dissolve more nutes more effectively?
Click to expand...
With the relatively low concentrations of dissolved solids in our nute solutions, pH's has zero affect on solubility of nute concentrate in water. Two part nute solutions are separate as they are not stable when mixed in concentrated form; has mostly to do w/ the buffers, I think.
