Does anyone know what I can do to resolve a fungal problem with my bonsai? It has white marks on some of its leaves and branches.

I got it as a gift and have kept it in the same room for a couple of weeks now. I did not realise the humidity had been so high. I had also watered it more than my Chinese Elm due to it having a larger pot.

I have since moved it into a dry room, as it is raining and humid outside.I have attached photos. The white marks on the leaves and on the branches are what I assume to be a fungus of some sort. The leaves most affected appear crumpled, as well.

You can cut off the infected leaves, disinfect sissers/hands afterwards.

Spray milk 40% / water 60%, spray leaves bottom / top sides. Redo this every 2weeks until its gone.

Thank you, it is working a treat so far.
