Are you using any organic fertilisers are you sure it’s not simply salt deposits. If your concerned turn the system off…… remove the AQUAvalve and clean with warm soapy water….. replace into the tray and then turn the reservoir back on when the water have been used in the trays….. don’t turn it on before the water has been used.
