Nutrients are like your daily vitamin. They aren't the main food source...the lights are. The lights you are using aren't doing enough work to justify the amount of chemicals you are using. If you only used plain tap water to this point with FFOF...you'd be way ahead of where you are now.
FF nutes are very strong. My lights are several times stronger than yours and I use 1/2 strength General Organics Grow/Calmag/Bi Marine. I switch to Bloom at end of stretch. I also use tap water and I don't PH. Chalk it up to a learning experience.
