Really Powerfull Newts

I am in the last weeks of flowering and i have added a new Newt Called Kool Bloom from Gen Hydroponics The Fox Farm Equivalant is Beastie Blooms.
The Kool Bloom is 0-45-28
The Beastie Bloom is 0-50-30
The Question is am asking is do you guys recomend these types of products
I used Fox Farms Tiger Bloom and have had great results and i am wondering if these newts would be good for finishing off the plants.

not sure bout the cool bloom but i use the entire FF lineup and have great results with a lil added molasses and bud candy
