We've had this plant ~6 months in the UK, it usually lives in the bay window so gets lots of sun. However, the edges of the leaves started to go brown, despite twice-weekly watering and reading online, it might be because it's getting too much sunlight.
We moved it away from the window for a few weeks, and it's still seems to be slowly dying. As you can see from the photos the edges of the leaves are browning, and the underside is off-color. We must be doing something wrong, any suggestions?
Edit: we've also been misting it with water daily to try and increase the humidity
