Don't know about blocking onions - never heard of them, but I do know that beetroot likes feeding with seaweed extract either in liquid form or as calcified.

Not sure, but too much nitrogen can make them through out lots of leaf and less root.  Maybe try potato fertiliser this year?

Where did you hear of these? Could they more commonly be called something else?

Not sure but about the term 'blocking onions' but there is a system of seeding onions in a block.
The idea is to place five seeds, one on center and the other four at 45% angles, when they hopefully all germinate the center seed is cut off and the four remaining seedlings are allowed to grow on. Transplanted as a unit the four seedlings will slowly push each other aside and grow to a full onion bulb without interfering with each other. This system allows more onions to be grown in a smaller space rather that growing by the row.
