Hi,
I'm subletting this house and the owner wants me to care for her plants, and I have no experience. She said to water the plants every Sunday with a medium amount of water. Whatever that means. She's out of the country and I can't ask her for advice.

After a couple weeks the plants downstairs seemed to always have wet dirt, so I figuring I was overdoing it and gave them a couple weeks off. They are doing okay now. They are different than the one upstairs, which is the one I am worried about. This one upstairs is growing increasingly brown, and I do not know if I'm overwatering or underwatering, as its hotter upstairs in this house and it could be its too dry. Anyway here is a picture of it.

I'm hoping for any watering advice, and would it help if I moved the plant outside for a couple months?
