If you used your tap water on your previous grow, how did those plants look?

I got in the habit of using calmag when I was using RO water and I use it now, in smaller amounts, just because my plants are healthy and I want to keep them that way.

Now I use calmag with my tap water. But I cut it down to 1ml/gal of water. Even when I was using RO water, I only used 3-4ml/gal of water. Personally, I think a lot of the additive manufacturers determine the maximum amount a plant can stand and use that for recommended dosage, so I usually cut down a little from their recommended dosage.

PharmaCan Reviewed by PharmaCan on . Question on Cal Mag Plus I just use plain old tap water. PPM are 170. Do I need to use Cal Mag per instructions on the bottle? From what I undderstand its only for those that use RO or distilled water but I also read that its good to have in case you notice a cal/mag defeciency. Would it hurt the plant using cal mag in my case given the ppm of my tap water. Peace Rating: 5
