Right side weaker than left

When Bench pressing my right side seems to be weaker than the left.
How do I correct this?
I was doing Chad Waterby’s program last night:- Bench press supersets with Bent over barbell rows 8x3
On my 6th set, my right side was lagging behind on the second rep.
I decreased the weight slightly but still had the same problem so decided to stop after 7 sets.
Should I use an even lighter load next time? or should I workout my right side on its own with a dumbell for a while to help it catch up?

It might be a good idea to try unilateral movements until your right side catches up. Ian King is a strong proponent of this, so you could take a look at his “12 weeks to Super Strength” routine here
