I see what Rasta sees. I don't see lights too close type situation.. If the lights are too close you will most likely see heat stress on large upper leaves and sides Curling inwards towarsd the center of the leaves themselves. I'd recommend getting a LUX Meter for you smart phone if possible, I found this an invaluable resource for my leds as I can identify light spread, hot spots, etc.this can give you peace of mind and then you know for sure.. But in my opinion I'm strongly leaning towards light nutrient burn.
