I've been searching through older threads and finally figured out that my first question should have been, 'how do I know if the problem is bacterial or fungal'? But then I found an answer to that to, where it was reccommended to see if peroxide makes it fizz, so I'm off to try that.
The upside to all this is that by accident I came across a picture that looks very much like a NOID orchid I have. It was a Blc. Hwa Yuan Beauty. This was the first time I'd seen anything that looked even close to this NOID I have.
