51cg

Hello everyone. I’m a proud new owner of a beautiful 10-12 yo Sweet Pea 51cg. I live in Miami, Fl in a first floor apartment without a balcony. I’ve had it for about two weeks and it’s already looking unhealthy.
The window it gets sunlight from faces to the north so it’s never really getting direct sunlight. I’m watering it daily, keeping the soil moist and even spraying the leaves and the trunk. I leave the window open all day while out of the house
I’m bringing it to my in-laws house because they have a garden and plenty of plants they regularly take care of so she can bounce back.
So my question is, what can I do to optimize the health of my Bonsaiafter she feels better??

Very nice looking tree! I hope it will do better in the future. I don't know too much about this species, but do you know how it was grown when you got it? For example, was it grown in a green house, outdoors, indoors, etc. The tree may not be getting enough light with a north facing window, and you may need to have it on a sunnier side of the apartment.
