Is This Mold?

[GuildedSpirit]

I need the input of those more experienced than I. I have several different batches of mead going and forgot to keep an eye on the air lock water levels. All of them got two low and now I'm trying to figure out if they've grown mold, oxidized, or something else. There's nothing fuzzy growing and no white film on the surface either that I can see. Had that problem before. More a buildup of white along the edge where the mead touches the glass. Very thin, near transparent spots on the surface, and some particulate sinking down when the carboys got jostled. I tried to get as clear a photo as I could. Any input/advice would be great.

For starters give them the smell test... don't stick your nose down in there, but waft some of the aroma up toward yourself. If it smells good or at least not fouled up, you are probably ok.

Going with your images
1 - That line almost looks like residual yeast or more likely some pollen and/or wax from raw honey.
2 - Looks like a pellicle formed and created an oxygen barrier. It's not so appealing looking and you can rack from under it. You can also use Kieselsol and Chitosan (Super Kleer) and it has, in my experience, pulled it and anything else (I can't tell if those are specks on the glass or in the otherwise clear mead) to the bottom that you can rack off of in a few days. Definitely stabilize when you rack.
3 - I can't tell from the picture, but if its not fuzzy it probably isn't a mold. I'd keep an eye on it to see if it gets fuzzy. If it doesn't you could probably rack from under it and sacrifice some volume to avoid that top bit if worried.
4 - It kind of looks like bits of honeycomb wax or similar. Cold crash it if you can to see if they'll drop to the bottom... Or use the fining I mentioned in #2 and they will almost certainly pull them to the bottom.

Oh excellent. Thank you so much. I was really hoping it would be something like this. I really didn't want to lose all these batches. I was using wild raw honey for all of these so the wax and pollen makes sense. Hadn't even thought of that. Thanks again.

Any update on how these turned out?
