I of course, meant 2 x 4 and not 1 x 4, either parallel
to the joist or perpendicular like the solid bridging.
I am wasting you 2 joists though by saying double the
joist at the edge with the blocking. It's supported
every 4' with stiff backs bearing directly on the solid
bridging that is in turn bearing on the outside plate
and as such is probably the strongest one in the
ceiling.
