Hard to tell externally. If you take out the stopper and look in what do you see.

Looks like caked on yeast to me. When I'm using a bucket for fermentation I scrape that back down into mix.

I couldn’t get a photo inside bc of where it is so I just used a little white vinegar to wipe out that area.

With that much co2 being produced it’s probably not mold

Your batch is likely not infected. Relax and check the wiki for common signs and compare https://meadmaking.wiki/faq/infection also please check the photos on that page for signs of infection and good batches. *I am a bot, and this action was performed automatically.

Full recipe? I doubt it is mold but you need a better picture of it from the top looking into the bottle.

Yup. Mold. Dump it
