1 gallon of water in an 8 gallon pot is about 12% of pot size and for a plant that big and watering every 4-7 days it probably should be fine. It looks pretty light colored though, like it could use some food though I think you said you weren't able to feed it. So what nutes are you using?
It looks a lot better to me than it did just a short while ago. Leaves aren't praying though, maybe try moving the light just a little closer and see if she perks up.
