When I do a solution change in my dwc I'll set the ph to 6.5 and for a week or better the ph will gradually drop until it gets to 5.5 then I'll start adding "up".......every morning because it drops overnight so fast.
What element is keeping a new 500ppm solution at proper ph that is not in the old 500ppm solution?
