@bradwww Can be done with the RoundSync app ( Round Sync - Rclone for Android | F-Droid - Free and Open Source Android App Repository ). It would be recommended to serve the FTP connection via a WebDAV server using it, to get around performance issues with file system sync on Android, then connect Joplin to it using WebDAV. That will require that you have a background / foreground service from RoundSync running all the time though, to keep the WebDAV server active.
