This is an interesting concept. On one hand, using a fruit juice won't add to the flavor- Those large molecules can't cross the root membrane. However, the sugars and organic acids (citric, acetic, etc.) can, and the plant DOES have a use for those.
As for the soda part, lowering the pH of the solution for your FINAL flush makes a lot of sense from a chemistry point of view. Salts and minerals are more soluble in an acid solution than in a neutral one, making a flush with a solution of, for example, carbonic acid as you are doing, quite a good idea to try. I'd like to see a side-by-side comparison between an acidic flush and a neutral flush, but I like your reasoning.
