Do I really need Cal MAG?

[Jmann567]

if you are using 'purified' water, it's 'likely' your plants DO need CalMag+ ... reverse osmosis water, rainwater, distilled water, and some highly filtered water, has removed calcium, magnesium, iron, and, trace minerals, that your plants definitely need ... calcium deficiency is fairly common ... just depends on how 'pure', your water is ... happy gardening :smokin:

So i was looking for the entire list of ingredients in Connossieur and found this https://www.advancednutrients.com/ad...?productID=466
so it does have calcium and magnesium! so then theirs no need for CAL MAG right?
