Mills A/B + Vitalize works great!Been a big fan of GH since pretty much my beginning. I used flora nova & floralicious. I've learned I can just step up my mls of the base & achieve the same result I used to get with adding the bloom additives. Now I feed 8ml per gal base instead of 5ml. Have had the same experience with Mills A/B. To be honest we did better with just the Mills A/B & cutting the bloom additives (pk & c4) out completely. I'll still use what's left of my floralicious but I probably wont buy it again since I figured this out.
