bought this Pothos at the Sill a few months ago. It used to stand erect and a couple weeks ago I came home from a short vacation where I watered it before I left but not on it’s normal day, and I came back and it was droopy like this. I water once a week with a little bit of plant food. I know my Pothos will eventually grow into a vine so not sure if it’s growing downward or im doing something wrong. Advice appreciated!
