I never use dark solutions in the early stages because you can't tell rot from staining.:wtf: I always use Hygrozyme to keep roots WHITE .Liquid Karma is the worst stain, but superthrive,Florisious plus stains also, and some kelp products.

definatly stop top feeding after the roots hit water or fill the baskets,blocks.Stopping top feed will prevent alge and white salt build up on the top of the medium

I run 4 min ON 1-4 hrs OFF feed cycles, depending

hope some of this makes sence
