BB is just a catalyst, and its very weak. You need to get some bloom food into her, If you like ff then I would recommend tigerbloom.. Works pretty good. One more thing, If your going lite on the bb then there is your problem. Your underfeeding them. If you look at the ratio's of bb they are like N 0.02, P 0.06, K 0.05 which is waaaaay low. If you have a ppm or ec meter then test it and you will see for yourself, If your gonna use BB alone then you need to double the recommended feeding amount
