No Bridgett, that is just normal were and tear. Anything from a poke with a stick (mechanical damage) or a bug took a bite or even a water drop magnified the sun and burned a small spot on it. Leave it be, it's fine and won't spread. If it were bigger and black and mushy, now that is rot ! this isn't. It seems the KQ that I have has several brown spots that look exactly the same as the ones on yours and mine grows like a weed. You'll be fine.
