Close up of leaf

Happy New year
How is the plant now? Don't wet the leaves incase it is a pathogen. Try to give it optimal conditions as much as posssible. Sorry this advise is so vague, its all I know to do for this. Other wise the plant looks good, at least when this picture was taken. Good luck

Could be many things. Leaves look a bit banded so it could be cold or draught damage.

The plant looks overall healthy so I wouldn't panic.

I know this is very late to answer. Been away from the forum for a bit and just getting back to it. The leaves still look the same. I used to keep it in the window so maybe it was from that? It's beee away from the window now for months. Doesn't seem to do mich growing
