Phalaenopsis orange growth on flower, insect or fungus?

[kristenrose]

Hello. I have been growing orchids for about three years now. Somehow, I have been lucky enough to have all healthy plants. I purchased a new plant and it has grown little orange balls on the flowers/buds, has withering buds (and a couple withering flowers, but most seem ok), some black spots on the leaves/base of the leaves, and while some roots are still green, some look rather unhealthy. I attached pictures down below.

Can anyone help identify what is wrong with the plant/a treatment?

Would this be bacteria or insects? **I have not actually seen any insects on the plant.

The environment of the orchid is indirect sun and cool, not humid temperatures if that helps.

Any help would be greatly appreciated!
