How do I know if I've added too much Cal/MG?
What would plants with too much Cal/Mg look like? Would the leaf tips be burnt? Would the sides of the leaves curl downward? A pict would help a lot. Lots of deficiency picts out there. Does it look similar to a deficiency? What are the characteristics of too much Cal and/or Mg?
I'm using Advanced Nutrients 3-part with RO water. Label says even when using RO water, Cal/Mg not necessary. I've heard otherwise. Please advise.
If you'd like to see picts of my leaves, please check my other posts.
Thank you all!

From everything I've read, there's no such thing as too much Cal/Mag. The plant will only take up what it needs. It won't burn the plants like with too much N.
One prob you might have with too much Cal/Mag, though, is a lack of something else. You've only got ~1000ppm's to play with, and if you put lots of Cal/Mag in, you'll have to short yourself on something else to keep the ppm's right. Also, as with anything, if there's too much of something you might get a salt buildup in your media.
Tips burned: Too much N?
Sides of leaves curled down: Too much water? Are you lettiing the roots dry between feedings?
You don't specify, but are you using Botanicare's "Cal Mag Plus"? Note that has N in it?

IME if you over do Ca you get what looks like an Mg deficiency.
If you over do Mg you get what appears to be a Ca deficiency.
I use mono Ca and mono Mg. so I can't say for sure about the calmag supplements.

I use RO water and had immediate pronounced mag deficiency. Cal-mag cleared it up really quickly. I've never heard anybody ever say that if you use RO, no need for Cal-Mag. I have heard the opposite many, many times.
