There’s some sort of brown spot on the leaf.

The overall plant:

The spot doesn’t appear to be pest-related but maybe it’s damaged from water left on the leaf after spraying. There’s no need to spray water on the plant for humidity – I don’t do it at all. I just water my orchids by filling up the pot in the sink, letting it soak for 5-10 minutes, then pour out the excess water.
The damage will never go away but it likely will not get any worse as long as you stop spraying. If the look of the damaged leaf bothers you aesthetically, you can cut it off I would just leave it on until it naturally dies off.
Good luck!
