I accidently mixed up my hydrogen peroxide with my Maxsea fertilizer, and I used it on my sundew seedlings, my scorps, and my capes yesterday. Will my plants survive?

In moderation I wouldn't think it would kill them. You probably were only using a 3% solution further diluted with ???. I've read that it takes up to a 10% solution to kill plants, but I'm no organic chemist/biologist...though there are some lurking around here. While waiting for them to comment I'd probably be flushing the plants with some distilled water or rainwater.

The problem is it was yesterday, and I only realized my mistake today. So there's not much I can do now.

Ok. I just figured a good flushing would remove some of the remaining h2o2. Was this straight-up peroxide out of a bottle or had you watered it down some?

It was 3% H2O2.

...and you haven't done any flushing?

I mean, your plants may be just fine, without flushing, but if I was worried about it I would flush them good and wait and see what happens. Who knows, it may super-oxygenate your plants and they may turn into giants...

How would I go about flushing seedlings? They're my main concern.

I’ve drilled holes in the caps of water bottles and inserted straws so I could water with some precision. Of course it depends on how densely they’re planted. Or, flood them and leave them unbagged for a while so the plants can dry off some. Or just don’t do anything and see what happens. They may be fine…. Wishing you the best!
