These once bountiful Pothos plants have struggled since moving 5 times through various light and air conditionsā) in the pandemic era. Since moving a month ago theyāre especially upset. Any idea on how to help them now? 2 years ago they went from extremely bright light to very minimal light. With this last move thereās slightly better (but still north facing) light but worse air quality, which manifests on their leaves as a thick film of dust. They were repotted from plastic to terra cotta around a year ago. The first photo is current; the second photo from 2020.
