oK so I watered again this time pH in was 5.8 came out 4.7 again. This time I just watered with regular tap water and used some aluminum sulfate to get pH sown. After watering I measured runoff was between 125-200ml for each 18 Oz cup. Im going to get a ppm meter from hottub store tommorow check my tap water but I think its good although the pH of the water is 8.5 so maybe its not as good as I thought.. Ok so attatched is a picture of the problem they are having. The leafs start turning yellow around the edges moving inwards and they get these black/brown blotches.
