The damage on the larger leaves looks like its from a few weeks back. It could be from too much watering/rain. Almost like water pressure bursting the leaf. There is an intimidating scientific name for it but I don't know it. The newer curled leaves could also be related to overwatering.

I would move it to a sunny and dry spot for a few days and monitor it routinely to see what happens. You should primarily look at the new leaves forming to see how they respond. Also check for any possible mites, thrips, leaf hoppers which may be causing the curling.
