Khan - Until they have roots, the clones have no way to take anything from the rockwool, so trying to feed via the rockwool is useless until the cutting has roots.

As you have discovered, it's kind of a balancing act. You want to mist the cuttings enough to keep them alive, while still encouraging root growth.

Home.grower - I use Clonex both for misting and for moistening the rapid rooters/rockwool. I've never used Hygrozyme but I guess it's a similar product and will work the same. My personal opinion is to stay away from any nutes until the plants have a decent root system. ...but I only make about 100 clones per week so I guess you should take that with a grain of salt.
