Thanks for the info but allow me to play devil's advocate as I want to learn the why and not just the what...I was by my local hydro shop that when using distilled water, I should add cal-mag to each watering as there aren't any minerals or whatever in the water. Not saying what you're saying is wrong, but do you have any logic on why he would suggest that? Thanks again for your ensight.

1st off, why use distilled water? Do you have toxic well water? Otherwise scrap that idea. If you are worried about chlorine effect on micro organisms, simply fill a bucket with your tap water and let it sit overnight, and all the chlorine will be evaporated.
Assuming that you are in soil, all the Cal Mag/nutes you add will build up, and never go away in a plant's life cycle, that is why I added nutes every 3rd watering, because the soil holds so much more than a plant can possibly use.
As far as minerals are concerned, use a kelp based supplement such as Advanced Nutes B-52, which will provide all the essential minerals and vitamins needed for optimal plant growth.
There are other ways to add minerals beside relying on Cal Mag.
Good luck
