is their add27 considered a bloom booster? making phosphoload redundant?
also, is the reason the add is pink is because it contains saturator as a wetting agent?
i am currently using a 5 gal rdwc with the dm gold line (a + b, add, zone, silica) my question is:
1. has any one used the gold one formula?
2. has any one used phosphoload?
