I currently am watering my plants with the Sunleaves Guano kit. Those of you familiar know that it has 4 different kinds of guano to take you through all stages, from germination to flowering. Well, I am finishing up the third week of flowering, and I am just starting to see the pistil formations. Today I was thinking about buying an additional organic fertilizer that is just for blooming. Is this necessary, or will the guano take care of everything? Thanks -cdub
