So I have a history of growing beautiful plants that don't produce, particularly broccoli, cauliflower, brussels sprouts, and onions. I plant my onions from sets, and when it's time to harvest, most of them have barely grown, some have doubled, and one or two have tripled in size. It's a disappointing day. My main stem broccoli looks like a cut floret you'd see in a bag of frozen broccoli, same with the cauliflower, and the brussels sprouts don't get any bigger than a pea even though the plants are huge. I seem to have no problem with potatoes, peas, pumpkins, root vegetables or tomatoes. I thought maybe it was a nutrient problem so this year I planted everything in straight compost with the same results.
