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.

Leaf tip discolouration 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. Rating: 5
