Hi all, I'm kinda new to the SS program, I'm a novice but not a completly novice I've been training seriouly for about 3-4 months, I decided to give it a try to SS but I had one question, is it beneficial to do hyperextension the days I do not deadlift (Workout B), could this help me to progress in the main lifts?

As a novice you shouldn't have to worry about accessory work like this. If you get to the point as a post-novice that you find you have a weakness in areas that back extensions target, there are better accessories than bodyweight hypertrophy work that allow finer control over training variables like the intensity, volume, and tonnage.
ah, didn't catch that you were doing the rows.
meh.... if you are doing the heaving-pendlay-barbell-row-things, those are more of a light deadlift. Probably skip the hypers.
bleh... If you are doing a super strict BB style row, and keeping your back in a nice isometric extension the whole set ... probably skip the hypers.
forget what I said and carry on.
