I'm gonna guess it has to do with the copper. When it oxidizes it turns black.

Try rinsing the plant and stopping copper and see if it stops.

I'm not 100% sure but that's all I can think of.

It's looking like this purple disease ppl are talking about. I'm curious if it's the copper sulfate... Please keep us posted
