MixPPM, the hydroponic salt-weight calculator

Why it surfaced

MixPPM is unusually specific: growers select the salts or commercial products they actually have, account for water tests and alkalinity, and receive tank doses to three decimal places. It also sketches a fuller workflow around predicted EC, mix logs, CSV exports, and saved recipes, though accounts and subscriptions are still in private testing.
