DWC and Age Old Organics.

I saw that FDD uses Age Old to grow his apple, or, I mean, pot trees. Has anyone used this line in a hydro setup? Specifically, Grow (12-6-6), Bloom (5-10-5), and Kelp (.3-.25-.15).

Also, for anyone who may have experience with this line, do you really use the Bloom during veg and Grow during flower?
