I did revise my message a bit so you may want to re-read it. This is a controversial subject. I will retry distilled water with mineral concentrace and see how I feel. Many years ago when I tried distilled water, We did not have minerals available.
Even rain water these days is acidic so where do we go to get real whole water? I know that my plants love rain water in comparison to filtered water.
I will keep you posted if I find more on this subject.
