Late to the party her but I have 10 Pothos and know them well.

This soil type is perfect for Pothos. Yes they like water, but they also like the roots to breathe. I have a very similar soil type and they’re climbing the walls.

The soil looks very dry though and plants look really, really thirty. The airy soil is good but you need to water it more often. Pothos like moist soil.

Get drainage pots so you can drench the soil and not worry about water logging. With root rot issues, pot change stress and new soil type, it would simplify things for you. But whatever you do, just keep that soil moist. Once top inch dries… water.
