Hi Bruce. You called what you need to use next a booster, and I want to rid you of that notion right away. FFOF is great soil, but it does NOT have the minerals and heavy load of other nutrients that your plants are going to need in bloom... you need a regular high performance nutrient program, and as @013 mentioned, @GeoFlora Nutrients fits the bill rather neatly. They are a sponsor here too, and I believe they offer a discount to members. It is good stuff and I have been using it exclusively for my last 3 grows and plan to continue using it. Geoflora will also work well with tap water and you wont have to worry about adjusting pH or any of that other nonsense. Geoflora is the easiest way to do an organic grow that there is... you won't regret it. If you go with just about any other nute program, plan on buying a pH meter as well as up and down adjusting chemicals, and spending more on filtered water.
