Is there REALLY any difference between the Grow and Bloom versions of this oranic additive? Both seem to be derived from kelp, and have all the vitamins, etc.. all the secondary and micro nutes. the formulas are pretty close, but represent nothing in my opinon: Grow: 1 - 0.7 - 0.6 Bloom: 1 - 1 - 1 The pppm addition is minor, 50ppm / gal at full strength dosing with distilled. Anyone wanna weigh in on the differences? Thanks
