Nutrients and Supplements ?'s

I am using GH 3 part system... I want to use Floralicious Plus and SubCulture for (rain drop system) VEG... and liquid KOOLBLOOM (is there something better) and SubCulture and CO2 (Ebb & Gro) FLOW...

Are these a good choice of products?
Do I Need to Flush during growth?
(what product[wont it kill HELPFUL Bacteria])
Should I use a Foliar Spray (what BRAND) even if using CO2?

That sounds great! I don't think you need the Subculture tho, because the Flo Plus has it all in it. Definitely use the Koolbloom for the second half of flowering.

HTH

yes i am using a hydroponic system.... very simular to the one on MR GREENS video... except i am using individual pots rather than a tray for the EBB & FLOW
