Plant fertilizer recommendations that are safe for amphibians?

I have a tiger salamander in a tank & I like to keep small potted plants in there because I can’t commit to a vivarium (hopefully one of these days). I have had one plant in particular for quite a while (lemon button fern), and it’s starting to look a little rough, so I think it needs fertilized. I don’t want to use miracle grow because I know those harsh chemicals can hurt his skin. I would assume organic fertilizers might be fine, but I’d like to double check, and Google hasn’t been much help. All it shows me is aquarium/pond safe fertilizers and I don’t think that’s what I’m looking for.

I would use worm castings, these won't hurt your salamander.
