By default FTPS (FTP over SSL, not to be confused with FTP/SSH or SFTP) runs on port 990. It also sounds like you're using passive mode - if so you may need to open those ports as well. It would make sense to me (although I don't know) that conntrack_ftp could only track unsecured FTP sessions since the only indication of a port change is in the packet data (which would be encrypted). Someone may know better than I, though.
