Yeah but they are brown, not normal for sure. Only time i've had brown bud is bud rot. Looks like some plants got dry to the point of dieing? If you are going to salvage that I'd cut that shit now. You spray'em with something right before the lights came on? Hard to say what to learn from it if you honestly have no idea what happened. Plants looked like they made it a long ways before they bit it, u in hydro?
