Okay need to know if I should still add cal mag to my nutrients when using an ro/di system with a re-mineralization stage which brings the water it makes to 6.4 ph and 88ppm . I do know that it adds cal ,mag,sodium,iron and other minerals to make the water better for people but not sure if it is sufficient for plants I was considering adding calmag at half the directed amount but just not sure if I can cause any problems by adding to much . So if anyone know much about this type of ro water system or just water chemistry in general that would be great.
