Hey bud- ...doesn't look like a nute' or ph issue at all,.. spots are white-ish, right? See any little black specks on the leaf surfaces anywhere? I know you looked for bugs, highly mobile ones, like thrips, can be elusive,...very small too, like this dash: (-) .....a better close-up pic would help,...another possibility is some sort of overspray of something harsh got on there,....
have a look for bugs as waira say 
Since the lower leaves are unaffected, I'd ask the same thing. Light burns look like bug problems
Thanks guys. I just can't find any buggers in there..even checked at night with an infrared camera. I think it must have been water drops when I flushed but I didn't think 96 watts of t5 could bleach, even at 1" distance. It seems to have gotten slightly worse overnight and is only on the top fans coming out of the main cola. The spots are light green. I don't think there are more number of spots today, just a little more pronounced. I'll just keep an eye on it...

Looks like Thrips to me as well. If they are there, they will most likely be on the underside of the leaves. You may also see some small black spots on the underside, which would be their droppings.
they sure are litte gits :twist:, iv not long Bom me room out,then after one of me girls got mosaic viru :dunno:,she had too go,let hope it just water but my feeling you got what muddy said,let me give the girl some Karma
