After looking at pics:

I am Flushing out my system today, and I will be putting nutes in. What strength nutes should i be running them on? I am using Technaflora Recipe for Success Kit, Been running them on 1/4 Strength nutes at about 500-600ppm. What Strength Nutes should I put in this time? I had my HPS 600w Dialed down to 300w, turned it up to 400w just a couple days ago, When Should I use full 600w?
