    our tap water has very high TDS, around 1600ppm, but most plants survive fine on it. I occasionally flush with tap water and my misting system uses the tap, so some does settle on the plants. I will try to take some pictures for examples, but not sure I can create small enough files or how to attach as I have been having trouble since I "upgraded" to El Capitan on my MacBook Pro.
    Hey Matt, There was a problem with viewing a picture on the thread you started. I started another on what sounds like the same problem. Hope you don't mind. This is the one.

    No problema, Chris. Actually I saw your post last night and it looked familiar, but at least the majority of your roots still look good. My root growth damage looks like yours, but with most of the new growths effected, turning dark or just drying up. I have a L. acne's with new growth that all of its new roots that seem to have died back. Not sure if I should try some root stimulants like kelp conc. or KLN or what to help. I am going to get a pH tester, just in case, but believe the tap water is pretty alkaline with all of the minerals and chemicals in it. I prefer to use rain water but it is rarely available here in the Sonoran desert, unless a tropical storm comes through (then there is plenty, ha ha). SO I use about 90% RO water , except in the misters and occasional flush throughs. I have a C. dowiana with three new growths I am really watching and basically ignoring, to see if too much misting or water could be the problem. Especially with dowiana's rep for fungus issues.

    Try to post a picture of the problem Matt. I'm sure someone will be able to sort it out for you.
