If you want to store empty values as NULLs into the database, you need to override JTable::store() and JModelAdmin::prepareTable(). Add following snippets of code into your component's admin/tables/nameoftable.php and admin/models/nameofeditview.php

admin/tables/nameoftable.php

public function store($updateNulls = true) {
        return parent::store(true);
}

admin/models/nameofeditview.php

protected function prepareTable($table)
{
        $defnull = array('array','of','columns','that','can','have','null','value');
        foreach ($defnull as $val)
                if (!strlen($table->$val))
                        $table->$val = NULL;
}
