Ackerman, you need to post closeup photos of the damaged leaves in these plants. It would be hard for any experts (and I'm not one) to help solve this when the leaves are hard to see..

Have you seen any movement on the leaves that could help identify infestation?

Also, are the plants in the bathtub because you rinsed them off?

I put plants in tub cause I'm afraid they'll infect others I have. The 1st picture is the dwarf umbrella tree that is adorable when babies grow but day before yesterday baby was growing and I found it browned out and dead. No movement seen. It does have this yellow, orangy colors around it. In center of leaves mostly where babies come from

Here's my Bromeliads that has two baby's coming in on sides. It's got same orange type colors but is covered with a white coating. Yuck

My beautiful Pothos I would wipe dust off. Now look, holes everywhere
