WillC said: Emi! Your plant is a Philodendron, not a Pothos. They are often mistaken for one another. Please provide some additional information.
Did you repot it? If so, when and did you remove some of the original soil?
How do you decide when to water and how much do you give it?
How far is it from the nearest window?
WillC said:Pothos and your Philodendron have similar light and water requirements, but Pothos are much hardier and more forgiving of some occasional watering lapses.
Let the top 1-2 cm of soil get dry before watering thoroughly enough that some water runs through the drain holes. The soil deeper than that should remain damp at all times.
The light you described seems to be okay.
