I bought a fiddle leaf fig tree earlier this week at Home Depot. It has been in my living room since I brought it home 4 days ago. I have noticed some reddish brown spots on the underside of some of the leaves, and I’m not sure what’s causing it. The plant is still in its original pot, which has drainage. I have not watered it since I got it as the soil is still damp an inch deep. And my living room is bright so it is getting plenty of light. Please help, pictures attached.
