I'll be honest, I feel fox farms nutes are for beginners who don't know better and don't mind over paying for bullshit.
the Big bloom is a bat shit and worm casting tea concentrate... its bullshit make your own from worm castings you can buy and some mollasses for better bang for your buck.
The Grow big.. is a nitrogen heavy fuel.. your own urine can provide better organic sources of nitrgen.. so can compost and other organic sources.. Get some fish emulsion for nitrogen..
And last but not least teh synthetic crap tiger bloom.. Its green, Why is it green? no one knows. It just is! And it sucks.. Get some Medina Hasta Gro 6-12-6 Better numbers better price and will actually benefit your soil instead of kill it like tiger bloom will.
If you wanna go full organic look into Advanced organics nutrients.
