Flyingteapot is your entire plant affected like that? It appears very similar to what I'm seeing, but hard to tell - can you post a closer up shot of new growth? Been talking to other growers in my area and they agree it's something with the water. Heard once people switch to trucked in water they don't have the issue. Still going to get better lab testing this winter on my well to find out what exactly it is. I know my water is hard (400 ppm) but hard water alone should not be causing this.
