I would Be Using Foxfarm Open Sesame, Beastie Budz, And Cha Ching! All formulated for the whole flowering cycle! I use Big Bloom For my Veg Mix Your ready for the Floweering Trio Now! You will see a huge differnce over the big bloom which is more of a veg Nute anyway! Nowhere near enough P and K to be an effective flowering nute!! Love the stuff as One of my supplements for Veg Though!!! Happy growing
