If you're not committed, I would say Lucas Formula + SoG. Simple, and if you lose a plant, you have a bunch more; plus, NO VEG!
If you are committed, there's Lucas with Fox Farm as well, use Google (site:rollitup.org fox farm) instead of the forum search, it sucks. LST/topping will better use your space without growing too tall.
Beneficials will do more than any bloom booster, while keeping the bad stuff at bay; check out MycoGrow Soluble. Beneficial Tea is best for microbials. Your environment matters more than anything, spend a sober hour in the garden every day; it's work, treat it as such. Drop your temps as low as you can in the last two weeks, NorCal loves purps, but they love it more when it's actually purple.
If R/O, Cal/Mag + Pro-TeKt will keep you going hard.
