Hi, I recently bought a ficus audrey but the leaves have started browning. I've had it for less than a week and in that time ive potted and fertilized it and had it in a southwest facing window. The room had a lot of bright indirect light but as the sun moved I noticed it would get some slivers of bright direct light. The room in my house it was in gets pretty hot and since the weather is dry right now so I tried to mist it about 3 times each day, however some of the leaves have started to turn brown and im unsure of what's causing it. I've only watered it once after i potted it so im not sure if its overwatering. The leaves that are browning, however, feel dry. I moved it into a northwest facing window that doesnt have the risk of bright direct light hitting it incase that was the problem.

Here are some photos of the damage. https://imgur.com/a/dAZJ0

Hopefully someone can help me out. Thanks.
