Any idea what this might be, or if I should be worried about it? I saw a post about something similar in soil that suggested it might just be excess salts drying. This was taken under a microscope and while there are thin white structures that look like fuzz, there are also larger crystals on the rocks. So I'm inclined to thing it's just nutes drying on top. Which makes sense since I know I didn't put enough of the hydroton in the buckets and can see the water during the fill cycle.
Anyway, if anyone thinks this might be a fungus or something harmful, please speak up.
Thanks.
