Ack!!! Frost Damage?

The very next morning after planting the garden, I went out to check on my little babies. This is what I found! Ack!! The cucumbers were the worst affected. The tomatoes, okra and loofah also had some damage. The broccoli and the established strawberries did not. I found an image on google that looks similar to this that is in an article about frost damage. It looks to me like everything will make it. This happened on May 14, today is the 17th, nothing has shriveled up and died yet. But, what the hell! I was all nervous cause I thought I was late getting my garden planted. Also, I didn't hear anything about a frost coming or going.
