I've had my Ficus lyrata for about four months now and I'm still figuring out the watering rhythm

I've had my Ficus lyrata for about four months now and I'm still figuring out the watering rhythm. It's in a bright spot near an east-facing window, but I keep second-guessing myself—the soil dries out faster than I expected, and I'm worried I'm either overwatering or underwatering. The leaves look okay so far, but a couple have some brown spots that showed up last week. Has anyone else struggled with this species, or am I just overthinking it?
