It's really the 6th. Jump SQ officially comes out on the 4th of every month in Japan, but you can sometimes find the issue early. In the English WSJ, it comes out on the Monday of the 4th or the Monday following the 4th. Next month, it should come out on the 10th in the English issue. If you really like the series, then you should spare the 99 cents to buy the issue and support its official release.
