GH is meant to be really easy my next grow is going to be GH flora nova 1 part bottle hassle free plus none of that a and b bollox lol.... It also buffers its self so no need to ph down Only problem is it's very thick but i don't care i don't mind mixing my solution for a bit longer.
I don't know where you got that information.
I use FloraNova Bloom all the way through, but you most DEFINITELY have to adjust ph down consistently as you would any other base nutrient.
It's not AN PH Perfect.
It's an awesome base nutrient, but does not buffer itself.
Check out my grows.
I just finished another 24 plant grow that I'll be putting up a log of done with FloraNova Bloom from start to finish.
Currently just started another round and am sold on using only FloraNova for base nutrient.
The only additives I use are Floraliscious Plus, and Liquid Koolbloom.
Those two are pretty much essential for good quality bud, and lots of it.
Peace.
