30 days left to flower what additives should I use if any. More info inside.

Let me explain what I am working with.

1000w hps in a cooltube
CO2 inrichment
Aeroponics @ 1000-1300ppm & PH @ 5.2-5.8
Nutrients used: Botanicare Pure Blend Pro bloom with H2O2.
Plants are doing awsome!
I will post pics later.

They have 29 days (about) left and I want to know if I should add some supplements. I have been using Botanicare and I am happy with their products. It's organic and doesn't clog my misters. I have been looking at their other products and was wondering if I should use them or another companies for that matter. Here are some of the other products:
Liquid Karma
Sweet berry
Sweet citrus
Power flower

I want to keep it organic! What do you suggest?
Also when do you other aero growers flush?
Much Respect
