Different hydro nutes for DWC?

Hey guys,
I just got questioned on my nute selection because I use DWC. I use Fox Farms' 3-part... Grow Big, Big Bloom, and Tiger Bloom. I've been doing this for years... is there something I don't know? What do you guys use? Thanks ahead of time.

aren't those pretty much organic? and contain bat guano and other such things?I see they have a hydro line .
