Cal mag question

Hi everyone, I'm about to start a grow trying coco coir and I read that they seem to get cal mag deficiencies so to correct this I'm supposed to add a cal mag supplement. If I'm already adding cal mag to my Nutes do I need to add more cal mag or would that be only if the deficiencies show up? Thanks for clearing this silly question up for me and merry Christmas.

What is the EC/ppm of your starting water?
What nutrient base are you using?
How much calmag are you already using?

I'll be using the technoflora line of nutes. Here is the mix chart I use. http://www.technaflora.com/downloads/USA2009.pdf

I would really need to have an idea how hard your starting water is, to recommend if additional Ca and Mg should be used.
I take it you don't have a TDS meter?

You should probably keep doing what your doing, and treat deficiencies IF they happen.
Make sure and water with nutrients every time, and water until you achieve roughly 20% runoff every time.
