So my summer squash is/was a beautiful display. One really took off faster than the others. She produced one gorgeous and delicious yellow squash and then... poof. Stops producing. And I mean, NO flowers, no buds, no nothing. It also turned a darker shade of green ... more like a hunter green. There is another yellow squash planted next to her that is now FULL of buds so I don't think it's a soil issue. And I read somewhere that if you allow your squash to get too big it could trigger the plant to stop producing.... but when I harvested, it was only slightly bigger than my hand. What could have happened?

This could be too much nitrogen. Excess nitrogen causes lush green plants and no flowers.
