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 corner but I keep second-guessing myself—some leaves look slightly duller than others and I'm worried I'm overwatering. Does anyone else struggle with finding that sweet spot? I'm in a tropical climate so I'd think it'd be easier, but the humidity in my place isn't as high as I expected. Any tips from people who've had success with theirs?
