Unhealthy pothos?

[privet01]

There are a lot of reasons plants turn yellow. Too much water, too little water. Too little light and too much light. Nutrient imbalance... lack of iron. Also too high a ph for the soil and/or water.

Just the light from a normal 15W fluorescent tube should be enough. We have a lot of different pothos all over the house and outside on the porches. They seem to tolerate a fair amount of bright sunlight. Though some that get lots of direct sun light all day long are slightly yellow. The ones just getting a few hours of bright light seem the best.

Ph might be the other thing I'd look at. I think they tolerate a low ph better than a high ph. But not certain.
