Rust fungus

[spellbound]

Think may have problem solved. Had a friend look at them and come to find that my PH pen was out of calibration. Done a good flushing then a fresh feeding so we will see in a couple days.

So that was the problem. Thank god it wasnt the fungus. No new spots showing-up. Will be checking calibration on my meter more often, was like 5 weeks since last calibration and temp of water/feed is important as well being that my meter does not adjust for that.
