Well after adding the next weeks nutrients into the reservoir the other night the plants got some ugly yellow spots on them. As soon as I noticed I added 2 gallons of water to dillute all the nutrient. It seemed to stop the nute burn as I posted over in the plant problems section with a picture. Thank god it didnt affect the whole plants and just a few leaves.

Other than that the plants look good and are still growing. I keep the ph around 5.7 or so. The ppm was around 400 or so counting the 60ppm from the tap water(havent installed RO system yet). They saw burn at 900ppm.
