Sherry, morning sun and lots of fog would not typically sunburn that Aeonium. We are coastal here and there's a whole lot of fog, especially morning fog. That fog is a great buffer against sunburn. The plant in my picture only burns at the end of the summer (the photo dates from late August) because that's when we tend to have the least fog, actually. In any case the sunburn will fade over time as the affected leaves are replaced by normal new ones, so I would view it as an indicator but not an actual problem.
I would not know what the dark spots would be otherwise. My instinct going just based on appearance is that it's sun, and not a big concern. The idea of water drops magnifying light is interesting but I don't see it as a real possibility given the water would not stick around on those leaves long enough to have that kind of effect. If those leaves are still wet over that big an area after watering, they are not getting nearly enough light or air flow, or something very strange is going on.
