I experimented using basically the same stuff which happens to be GH's Bloom (pink stuff, 1,6,4 or something like that). I added an extra teaspoon per gallon to GH FloraNova Bloom. This caused the bottom of the plants leaves to turn brown (burned them, too much nutes). I talked to GH reps and they said that it may do that. If you're already using GH stuff I wouldn't bother. They basically don't need any more nutes and your best bet is to spend the money on some Humboldt Gravity instead.

I already use the general hydroponics nutrient for flowering (one part total bloom).

its Advanced Nutrients, and yes I think its one of their better products for flowering cycle
