Leaf spots won't go away any ideas? (pics)

[glockstar21]

I have no idea what is going on with this plant. It’s the only one with this many spots on it. Even the new leaves on the cola have them. Is it just a dalmatian plant or what’s the deal? It’s treated exactly the same as the rest of the plants in the room but the only one that is doing this. Thanks for any input.


extra info:
Indoor and I’m using a 250w hps supplemented by several cfl bulbs. I have 9 plants in their 3ed week of flowering. Ph is around 6.8 and my temps are between 80-85 with the lights on and 70 off. I was using 10-60-10 nuts at1/4-1/2 strength but have cut back a little. There no bugs what so ever in the room I am sure of that, and the underside of the leaves look like the top.

looks like it could be damage from thrips, or some other insect

looks like maybe a PH problem.

If you rub it does it stay on the leafs?

80-85 is too hot..get your temps to about 78.
