350ppm about 6.8-7.2ph. running on 3 300 watt hps lights, added some nitrogen last night and less watering and today I see quite a large improvement. Im not sure if its nute burn because it would effect all of the plants?

Theres your problem, pH should be between 5.2-5.8. Yours are way out of range. You must get them within range. You also have some mold on your Rockwool. Don't over water them and add some hydrogen peroxide to the water to help inhibit mold/fungus/algea like that.

Try a tsp or two per gallon of water.

With pH down from a hydro store, hardware store, nursery or pet store [in the fish section.]
