You didn't really give much info, so its going to be hard to answer your question, but I'm assuming your stressing out, so ill give it my best shot.

I don't know how long along you are but it sounds like it could be nutrients burn. Your pH is on for soil, and the only other thing I could think of would be ozone damage. Yellowing in flower is normal, but not the rust. If you're pretty far into your grow you may want to wash out your soil with lots of water and no nutes for a day just to make sure your plant hasn't been locked. When I use to grow soil, I often saw that over fertilizing often caused nute lock, and that a day after cleaning out the soil, the girls would get greener, and start producing better. Good luck.
