I have this silvery, fuzzy, something has been apparently growing on the surface of the coco. It is recent development. It actually started on cuttings in start mode. Clean coco plugs and rockwool started getting this on it and all the feed they got was pH water. Then it continued after initial potting. I've just been sweeping off a top layer of coco containing it into the garbage, but it comes back.
Here are some pics of it. My camera wouldn't get close enough for a naked eye look and my handheld digital scope only gets a 20x magnification. So, to see what it looks like looking down at the soil, you'll need to zoom out.
To me, in these closeups, it looks like webbing. Is there a varmint that belongs to this stuff? Is it a mold? It doesn't seem to be effecting the growth of the plants, but I don't like it!
This is the first time I've ever seen this so I am lost, but there are so many of us here, I am sure someone has seen it before. If anyone can identify this, it would be very helpful.
Edit: Some pics looked too much like another to waste disk space posting them, so I removed them.
