Ale,
I'm trying to figure that one out myself. I got it on my 7 seedlings that are just on a top feed recirculating drip. H&G + cal mag plus at 700ppm. PH 5.7-6.4 (it raises in about 3-4 days). At first I thought it to be possibly PH. Then possibly a watering issue.I'm still not comfortable with the idea of the wet rockwool cube in the quick drying hydroton, so it is always a tossup as to which media to watch for moisture levels. I will shoot up a pic when I get a second with the camera.
