I believe that the producer is a drip system if my memory serves me right, do you have the drippers dripping directly onto the Rockwool? If so this can be a problem depending on how long your drippers are on for.

BlueBear,

I didn' soak the clones in 5.5pH water before adding the 1 inch cube into the 3 inch cube.

The hydro system is a combo DWC/Drip system. The drippers do drip directly onto the rockwool. However they only go on twice a day for 5 minutes. So I do not think the rockwool is the problem becuase it stays relatively dry most of the day.

I do know for sure now that this is a root problem.
