Yup, I thought of Drdawg soon as I saw this, too. He knows a lot about fiddle leaved figs (ficus lyrata). My first thought would be overwatering. I assume it's a larger sized pot, and once a week can be a lot of water for a large indoor plant - depending on how much you water it each time. Rather than a particular schedule, I would only water it when the the top couple of inches of soil dry out. It may be once a week, or it may be once every few weeks, but doing it that way, the plant will let you know when it's thirsty.
Plus, it could also be from just being in a new location and will need to acclimate to its new home in your apartment - and then being moved around several times from your living room to bedroom and back to living room. Poor thing doesn't know what's going on!
It does sound like the light from your bedroom would be best for it to be happy.
