So I've been using ro water for about 2 months now and I'm starting to see whats looks like a mag deficiency. Is adding cal/mag a must with ro water? I'm using fox farms nutrient which do contain cal/mag but I'm still having issues.

I need to add cal-mag regardless of whether or not I use RO water. I am not using RO water now because my water is low in dissolved solids, but still need cal-mag. If you need it, add it regardless of the water you are using.

If its not a ph issue only and your certain its a calcium or Mg problem then add it.

Just be sure before adding stuff to try and fix it. You don't want combined problems..

You will want to add Silicate to an R/O water mix also, and yes, mg is MUCH needed in R/o

I have some questions concerning soft water -- what is it? Is it better than hard water for the plants? Is it a concern at all? Should adjustment be made? I'm already missing the lake....

Peace
