You can us that brand if you want. However, those nutes are formulated for general purpose gardening, which may leave you with an imbalance of needed nutes and other elements present that aren't needed by Cannabis. Cannabis is a very need specific plant, and if you want them to grow to their best potential, then you need nutes that are formulated specifically for Cannabis. I do like the others above and order all my stuff from Amazon. Trust me, no one is going to follow the stuff you order to your door to ask you why you are getting that. Logistically no agency can do that, due to the thousands of products that get shipped everyday. If you want to buy local stuff, then I recommend that you look into the organic soils/nutrients. Espoma makes all organic nutrients and they sell at home supply stores. Plus those come packed with the microbes that are critical to organic growing.
