I went to check on my hibiscus and now a lot of my leaves are like this, why? Is it pests or is it not getting enough water? I did skip a water but would it decline this fast. I did have to treat her for spider mites two weeks ago with soapy water but I thought they were all gone and I’m not seeing any. Please help.

I just bought two fertilizers, one for my spider plants and one for my hibiscus and it left me without money for a third for my caladiums. Will either of these work? Or is it better to wait until I can get a different one for them?
