Big Bloom is a good nutrient but you need more. I think you are supposed to use Tiger Bloom or Grow Big too. The recomended NPK to flower pot is 10-30-20 or 1-3-2. Big Bloom is .01-.3-.7 it does not have enough N,P or K by itself. Tiger Bloom is 2-8-4 which is closer to 1-3-2 or 2-6-4. I dont use FF by itself anymore because it seems to create deficencys because of the wrong NPK. I mix OpenSesame 5-45-19 with Supernatural Bloom 14-9-19 to make a NPK of 19-54-38 which is very close to 10-30-20. The nunbers are percentages so 19 is 10%, 54 is just under 30%(57 would be 30%) and 38 is 20%. So the NPK is very close to 10-30-20 and my plants love it! Some members do use FF and someone will help you out with the BigBloom. Good Luck~!
