I’ve had this rubber plant for several years, during which time it’s grown from a baby plant to over 5 feet/1.5 meters tall. Recently the older, larger leaves like this one have developed these brown patches and begun falling off. Is this to be expected, or should I be concerned about sun exposure, or over or under watering? If it’s helpful, it’s also been in the same pot for several years.
Since it’s been a little while, since it’s last repot, I’m thinking it might be root bound, and sometimes when this happens, soil becomes compacted and doesn’t absorb water properly essentially dehydrating the plant. I would check and see how the roots seem if they’re pretty compacted in there or coming out of the drainage holes repotting should fix it!

If I’m repotting in winter months, I’ll repot a day or two after a watering day and then wait a little longer till the next water to give it time to adjust. A good rule of thumb is if you have 50% (or above) roots to soil ratio it’s time to upsize. Wait a day or two after a watering and you should be able to gently remove it from the pot as a whole to check the roots.
