I have a few pothos. They were all so full and pretty with many, many leaves but the last few months they have been dying and I am not sure why. Can someone tell me if they can be saved and if so what to do? I have been taking care of them the way I always have: careful not to over-water, etc. But all of a sudden they just start wilting, leaves turning yellow and brown, stems getting soft and yellow and just falling off.
I'd take as many healthy cuttings as possible and start over. It sounds like it's picked up a fungus or bacteria most likely now in the mix by what you are describing. From the leaf close ups I reckon there's definite powdery mildew and that needs to be removed. You can apply fungicides for this and it wouldn't hurt to get some and try: but I'd still take cuttings and be sure to spray them. Maybe taking cuttings and repot the remaining lot into fresh mix wouldn't hurt.
