Im using something, maybe the same thing as u, for veg on 3 soil bagseed and 3 DWC Hydro bagseed. The Pics are of the stuff im using. My babies are all 2-3 weeks old so im only about 1 tsp per feeding. The stuff seems to have good nutrients in it judging by the lable and the fact that its 100% water soluable, and made for sprayer type systems it wont clog my airstone in the DWC. But, Im no pro... one of my weaker plants got burned bad but all the rest seem to love it and look perky and healthy.
