Causes of leaf drop.....perfectly looking leaves.

I know this has been answered a zillion times....
Got a green island ficus and a varigated jade that are losing perfectly looking leaves......here in virginia it has been a bit rainier than normal of late.......some areas got 3 inches of rain today let alone.
Thought on the leaf drop?

My ginseng ficus lost some leaves this Spring like you are saying.  Root inspection revealed it rotting badly.  It went to tree heaven.  No pest discovered.  No external signs.  Just mush inside.
