Installing 3/4" T&G subfloor over 11-7/8" engineered wood I-joists and not sure how skinny the last row of subfloor can be. If I make no adjustments I'll have a last row of subfloor that is only 10" wide. While that row will sit on I-joists that are 16" on center with one 2x6 squash block at each joist, not sure that's wide enough. Can adjust at center beam to make it closer to 2 feet wide, but a lot more work and will waste material. Any thoughts?

Skinny subfloor row...
