What the hell is that?

Cant be too sure with the amount of info you gave us. The more pics, and more info the better someone will be able to diagnose your babies. But to me, the leaves look like maybe a slight ph change? The spots... Well, I have no idea where that could come from. Maybe a nute def or over?

looks a little stressed, have you transplanted recently? are you over watering? if not, could be a few other things, ph imbalance, maybe even calcium deficiency or some other deficiency/over feed.
