Disappointed with onion sets...

the sets give nutrients to the shoot and stalks and you will get a new bulb. "The original set is not a start of the bulb at all". Please be patient and hope you get good harvest. And on the other sets you mentioned not looking good
are they rotten (press slightly the set and are they squiggy)?
if not bung them in and you will be surprised to see them grow good.
In my very short experience and testing drier sets are better to start with than the wet fleshy sets.
All the best
