Crispy Leaves

Hi everyone. I know what your going to say. "LIFT YOUR LIGHTS!!", but, this plant is actually about 6 inches further away from the lights than the rest of them, and the rest are fine. Every leaf on this plant is like the picture. The leaves are green with yellow spots in between the veins, and the entire leaf is kind of crispy feeling.
Help! I'm running 1000w hps 24 inches above the canopy. I've got cooltubes, so the temp at the canopy varies from 70 to 80 degrees F.

That leaf just looks mutated to me.. Could be bad genes cause the leaf has a nice color to it although you did say crispy so its probably something else. Did it start out growing weird or did it start in a little later in the grow?

There are two plants that were like this from day 1. one of them isn't quite as bad as this one. They are barney's pineapple chunk.

I'm using ffof for soil, and I haven't added any nitrogen. I've only used the big bloom very sparingly. here are some pics of the actual plants.

I've read that calcium def can cause deformities in the leaves. I crushed up some calcium tabs and added them to the soil with water yesterday.

Is this affecting the whole or just part of the plant?
