I have an almost identical problem, also with a pothos. I was told that the issue is caused by salts accumulating in the soil, or by poor drainage. One person told me to leach the soil and use bottled water. Another said that switching to a soiless growing medium would work.

The curious thing with mine is that the affected plants were rooting in plain water. There might be some truth to both their assumptions though because I've learned that the well water here is high in iodine, among other things, and it leaves a white film on washed cars, dishes, windows, etc.

Someone with more experience will be able to tell you more, I think, but thoroughly leaching the soil, and using filtered water thereafter might be necessary. I'm moving my plants into filtered water. Meanwhile, this is what mine look like.
