My first reaction is "Very clean and green!". Both the bulbs and the leaves look flawless. I'm growing no onions but when I do, I get a lot of brown tips on the leaves. Do you know what the varieties are?

The first picture of them after harvest are of onions I bough locally at our Farmer's Market. The second is of my garden.

I planted a mix of White and Yellow Onions, though I mixed up the placement and now won't know which are which until I harvest them, lol. I would have thrown in some of the other varieties but the Nursery was selling onion sets by the pound this Spring and of the two pound I bought, one yellow, one white, most ended up in a soup.

We're at over 90s this week, with 100 expected today. The heat is doing a number on the exposed bed of onions. It went from this

To this

I'm going to harvest these this weekend and weigh the sum out, with pictures.

This comes back I think, to the changes in how we grow food, I expect to occur due to climate change over the next few decades. Plant early with the risk a late frost will hurt your seedlings, then harvest at the beginning of the hot months of Summer. Replant in late August once the heat snaps, and either harvest another crop late at first frost, or over Winter the plants that can.

Or use containers which allow you to move them from full sun to some shade for protection.

The five onions I've been experimenting with in a container are doing ok, and look like they are bulking out. I recently added about an inch of compost to the container, since it seems I didn't plant them deep enough, their bulb tops were showing.
