The branches of my aloe vera plant seem to be draining and the plant itself is turning orangish brownish, why?

My friend gave me a baby aloe vera plant, I’ve had it for almost a month. She repotted it before she gave it to me. It was doing fine until last week… I noticed that one of the branches was starting to drain, and yesterday I noticed that it was happening to all of them. They were paper thin in the top half and normal in the bottom half. It is also starting to turn brown.

I have it sitting in my living room window, where it get direct sun every afternoon, and I’ve been watering it about once a week. Should I be giving it something like Miracle Grow? Any insights? I do no know much about this plan thing, but I dont want to have to explain to my friend that I killed my aloe vera plant she gave me!
