mottled looking leaves

They come this way, even when younger. its like they can't turn darker green fast enuf or something. is that normal? Some of the lighter spots will eventually turn brown while the rest of the leaf seems mostly healthy. Hydro setup adv nut sensi a/b ph 6ish. Seem familiar to anyone?

Wow I have never seen that before, what strain is that?

Well, I'm going to rule out nitrogen (as that would typically show up on the bottom of the plant first). I would suspect the micro nutes. Specifically Iron or Calcium. Are you adding calmag? Foliar feed with a micro nute spray and penetrating agent and see if they bounce back.
