the 15-30-15 and the 10-10-10 are no goes as they are to high in nitrogen for the flowering stage. Go with with the 2-5-2 and the 5-7-5 if thats all you have. If you can look for Bloom Boosters that are high in phosphorus and potassium. You vegged for the right amount of time it was probably the floros... you have the HPS now so they should be ok.
