to answer your question toph, u shoudl read the NPK numbers on the label, for example my ferts numbers are 24-8-16, my fert is good for vegatative growth because it is hight in its first number: Nitrogen (N), the second number, Phosphate, is low, and so is not as good for flowering as other ferts. if ur second number is ur higher number of the three, then it should be ok for flowering..
