Hi Guys,
Can you take a look at these pics and tell me what I should do about the slight discolourations on parts of some of the leaves? It looks silvery but that might be because the HPS is shining on it.
Any advice would be appreciated, cheers.

Hard to say could be over nutes or light burn. Pics are not to great and not enough info on your setup. You need to get pics right when the light go out (with flash) and tell us more about your setup.
I'm with loc nar on light burn even though the pics are badly-lit.
Over nutes would present as a more pervasive problem, with not just those few small patches, but the tips of the leaves would be browning.
Hey Guys,
Some new pics of leaves we removed from the plants today. Any ideas what could be causing this kind of discolouration?
We went onto a 600w HPS for the flowering stage a few days back so our immediate thought was light burn but the tops of the some of the tallest plants seem unaffected and there doesnt seem to be any uniformity to the affected leaves. They are dotted around the grow room on various plants.
Any help would be greatly appreciated.
***Growing ICE and Bubbleicious in mylar coated room approx 5ft wide and 7ft tall with intake and exhaust fans, Temp at 76 degrees, 600w HPS for flowering, using Aqua Vega A + B nutes on full strength, full NFT setup with rockwool cubes***
The green looks good. One ?. do the leaves overlap and cause condesation ? If so the light will burn the water spots but it just doen't look quite like that. It's a hard one. You don't see anything on bottom of leaves do you ? like a bug or spider. Either way doen't look real serious. Get us some pics of the whole plant , might help more.
