Black Spots on Dendrobium, Tiny Yellow Spots on Paph

[Ray]

The damage to the dendrobium is typical of sunburn. There is nothing you can do, and there is nothing you need to do.

The damage to the paph leaves looks to be a bit of minor mechanical damage, possibly due to insects, but might be due to a pathogen if water was left standing on the leaves. If it does not expand/progress, that's probably one of the two. If it does, a picture of the true extent of the damage can help.
