Fatsia Japonica orange hairs on stems

[Greentomatoes21]

Please help!

I was bought a fastia japonica for indoor growing in a nice pot.

Some of the leaves have curled up and died. Others look large and healthy but on closer inspection there are a couple of dark spots.

Some of the stems seem to have a dusting of a very tiny orange hair-like substance. I can get it off with my finger and blow it away.

I would love this plant to survive! Anyone have any ideas what's wrong?? I don't believe we have over or under watered.

Thank you!

Can't seem to attach pictures on the app, sorry

New leaves often have this orangey appearance. Some of the leaves are probably suffering from the dry air.
I grow mine outside and it’s quite robust, although it does like a lot of water.

I think of them as outdoor plants….

Oh, OK, thank you! I have set it outside today, maybe that will help! Some of the leaves have spots now ☹️

Also watered it a bit more. How often would you say you're having to water in summer? (I'm in UK, currently very warm).
