Most probably spider mites (I can see some telltale speckling). If it doesn't already have them now, it's just a matter of time until it does!

could be.. i surely cant see much of anything in this pic.. and im not saying its wrong ...

but it also looks like it might have been left out in a parking lot in severe heat for a day or so ... sunburnt ....

and that is something that can brown leaves in a matter of hours or days ...

as compared to some bug infestation.. that would have had to have been there for months to build the requisite population for such damage ...

They do best outdoors where they can become invasive given enough time and the right conditions.

Here was my last one that I tried keeping indoors and finally left it outside in the original pot inside a much larger pot. It did a lot better here than indoors for winter.

Some start reverting though.

Dug up this hosta last year and along came some ivy

Not sure who will win here - the ivy or the Asian Jasmine.

One I put out 3 years ago is getting a nice spread.

They become addictive though.

Don't know what is happening to the middle shoot.

two different types from a friend plus the hardy begonias (this was in April). All those plants are in an aluminum pan and been sitting there for 3 years now.

Same pan July 1st.

Anyway, move your pot outdoors, trim off the dead and damaged leaves and keep it watered as needed. You will get lots of growth.

Not with spider mites!! Chances are very good the plant came with these tiny (microscopic) creatures already present and the damage they can do is extremely rapid as well.
