I don't pre harvest flush anymore. First of all, I make sure my soil mix is rich enough that I really don't use much in the way of additional ferts or supplements that will build up in the plant. Second, it's a pain in the ass with my set up. I merely stop feeding them and give them only plain water or molasses water about 3 weeks before harvest. Then I let them dry and cure properly. No nitro/chemical taste. This last batch tastes like lemon. Yummy. I've gotten LOTS of compliments on the taste of my herb.
