All the guys at the Hydro shop in Hollywood are hyping this line of nutrients. I'm about 2 1/2 weeks into flowering and so far things are looking fantastic.
BTW ignore the week 1 pre bloom, use your flower nutes, not grow nutes for that first week. And if you need to stop verticle growth use The Beast, it works great.
I'm using the same nutrient line myself right now for the first time. Here is a link to the feeding schedule http://www.floracorp.ca/images/nutriplus2008en.jpg and the company website www.floracorp.ca. You should be using your Start, Grow A & B, Black & Gold right now and Thrive if you have it...
