Chilli Plant's leaves

How many hours of direct sunlight does it get per day?

Spider mites? They're also not likely to be getting enough light but that wouldn't cause the speckles.

Thanks for the replies

Its kept on the east facing windowsil so gets, well not much during the winter months I must say.

This will make the plant weak. Also houses are typically too dry for growing many plants. A chilli is not an indoor plant which are typically selected from those that grow in understory low light conditions.

The weakness will also make it more susceptible to diseases and attack by insects and mites. Chillis and capsicums are warm climate and warm season plants that like full sun to do their best. You don't say where you are so I am guessing somewhat but you might do better to grow them as an annual outdoors or at least in a sun-facing (away from the pole) window.

Or if you just want to grow them as a decorative plant, supplement with a grow light
