This is my first attempt at a hydro grow and I noticed yesterday that my baby has spots on the leaves. I checked the PH and it was fine...right at 6.0. There are no nutes in the water. I have a pump with tubes going into the net pots to give a continuous flow of water to the rockwool. Two big airstones in the water create lots of bubbles. I am at a loss...any ideas would be great!
