Give which a try? Tigerbloom or the water solubles?
Open sesame > Beastie Blooms > Cha Ching... They have been advertised as complete nutrients, but they are sold more as additives. You don't have to get them.
I really think you should finish up your NOVA grow for what little veg time you need and try the new bushdoctor microbrew and tiger bloom for bloom. if you want a flower additive, just get open sesame and beastie blooms. screw chaching.
So if I were to recommend how you spend your own money, I'd say:
Tiger Bloom
Bushdoctor MicrobeBrew
Open Sesame
Beastie Blooms
