As I mentioned earlier in my log, I am getting my food pre mixed and PH tested. I ran out of food for 4 days and had to feed my ladies Tap Water (which I left standing for a minimum of 24 hours). On the second day that I restarted feeding I noticed some leaf damage and I wanted to confirm that it is the Tap Water that has caused the problem or if I should be looking for another cause. The leaf damage seems to have slowed down since I switched back to the food.

The damaged leaves (about 4 on one plant and 2 on the other) either get minor damage on the edges (like pic 1) or get a "rusty" sheen all over the leaf before looking like the second picture.

I have a PH tester arriving later today, so if it is my tap water, I should be able to eradicate the problem.
