Yellow brown rust color

I have posted before, and people thought it was a nute problem. So I flushed my plants for 3 days,and then added very little nutes. Problem seemed to get a little worse. Plants are 6 weeks old, using a bubble boy hydro system. Nutes are general hydroponics grow. I have about 10 cfl on it and the ph is 6. A lot of the leaves seem fine. But some look like this.please any help

check that out might help abit.. also a noob so cant really give a good opinion

Does look like a burn to me. Can tell by how dark green your foliage is. At least too much N.

Btw, you will have to look to new growth to know whether your changes worked. Leaves usually don't repair themselves.

I'm not sure about hydro, I grow in soil, but it looks like a Cal-Mag def..brown rust spots w/yellowing..If it was me, in soil, I would flush my medium and hit it with mild nutes and cal mag.

The dark green foilage could be genetics..

EDIT: I do agree with the second half though, leaves won't heal
