Moisture on my Leaves

So i just got home from class and, as usual, the first thing i did was check on Optimus and Prime (My 2 sour diesel plants) and i noticed that on the top set of leaves closest to the light there was a bit of moisture, like a cluster of water droplets. I'm growing with an ebb and flow hydro system so its not from watering them or anything. I have no idea where they came from, is this normal? I really don't know cuz it's my first grow but if anyone could shed some light on the situation it would be appreciated. One more quick question, how do you know when your stretching your plants? Just big gaps between the set of branches or what?
