Thanks for all the details!  Here’s my assessment and recommendations:

• This plant is called “weeping” for good reason: you should expect some degree of leaf drop.  But there is a more obvious reason why your plant will experience significant leaf drop – its current light situation is 100x less (yes, a hundred times less) than where the plant was raised.  If you use a light meter on this spot, I estimate the light levels would be 50 FC most of the time.  The commercial nursery where Ficus are raised typically gives them 5000 FC most of the day.  Most indoor spaces will not have anything close to this level but during the warmer months of the year, Ficus will do well outside in a partially shaded area.  If you only have indoor space for the plant, it needs to be right in front of your largest and sunniest window for the least amount of leaf loss (and there will always be some leaf loss)
• When your plant is in a better light situation, you should use fertilizer on a regular basis – my recommendations here.
• When your plant is in a better light situation, the water usage will be faster, which means you will be watering more frequently.  You can continue with bottom watering if you want but I find it to be too time consuming.  Pouring to evenly moisten all part of the soil is sufficient.
