Fiddle leaf leaves yellowing and falling off 💔

Hi all! Looking for some advice on my fiddle leaf fig. I’ve had it for about 4 years and it just put out a new sprout at the top, which seems healthy. However, the bottom leaves have been slowly falling off and some are turning yellow. It’s been in the same spot with the same light for years. I probably err on the dry side with watering, and I fertilized about a week ago.Is this normal aging/life cycle behavior, or does it sound like a watering or even temperature issue? Any insight appreciated! 💚💚💚
