I've used the Big Bloom in my outdoor grow before. Good stuff but kind of expensive. The other 2 are basic chem ferts, IMO. I haven't used them myself. I did look at their feed charts for soil and to me it seems like a lot of fert per gallon. Do you check ppm's/EC to know how hot your mix is?
I don't see where they give a ppm/etc. range.
What strain are you growing? Density is often a genetic thing...though other factors can also come into play. Pics always help. Is she healthy?
