名媛直播

Hey peeps,
I have had my 名媛直播 for nearly two years. Recently, its leaves started to show yellow dots, and they're getting more and more yellow(ish) every day that goes by (pictures have been attached below). I tried different doctors, one said it's been sick from cold weather, one said it needs more water, one said it needs less water and so on... And yet nothing worked and my bonsai is getting more and more ill...
I was wondering if anyone could help me out with this matter.
Thanks in advance, and highest regards !

As it is a Ficus it is not going to affected by the weather outside. Have you checked to see if there are any insects or possibly Red Spider? It looks like some sort of infestation.

root issue; Probably calcium buildup. ossibly rootrot. Probably overfertilized of too little fertilizer.

Ask a forum on houseplant care I would recommend, as this has not much to do with growing bonsai. They will be able to help you better.
