How would plants with too much Cal/Mg look?

Fractalicious · Jan 11, 2013

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!

Yes pics would help, any burn would be tips and spots around the tips eventually all burning no matter what you are pushing through it. Deficiencies are much easier to detect with specific patterns.

Cal/Mg burns are rare as they are much needed and used by the plant, but it can and probably does happen. I do 1ml CalMagic per gallon of water no matter if it is just RO water or nutes and RO water. I never have an issue or deficiency now.

If you are in DWC with AN also, you are probably TOO hot on your nutes as well, and probably more likely the cause.

excess can cause other important elements in the nutrient solution to "lock-out" and become unavailable

Nutes only at 500 ppm. Is this too hot for DWC? Is there something special about AN, or would 500 ppm be too hot for all brands of nutes?

i know from experience professor is right. too much mag will definitely lock-out the major nutes your plants need and they will look very sick. middle fan on leaves will be smaller or will fold too.

I never go over 400-500ppm at END of my vegging... especially when RH is low.
