The best Nutrients I can get?
I recommend Jack's Classic All Purpose for veg, and Jack's Classic Blossom Booster for flowering. All 100% organic, can be found at most local plant shop/nursery's. And is used by most pro growers, it needs no supplements as other nutes do, which says alot right there. It is also relatively inexpensive, and designed for cannabis (has all the needed trace elements).
Roughly $15.00 for both containers, here is a link you can find a location that sells it near you:
Buy Jack's Classic Plant Food -- J.R. Peters, Inc., Fertilizer Manufacturer
And another thing, just because a company has a snazzy label on their bottle DOES NOT mean they make a better product! It is called marketing, and it is cut throat business they do. Also, if nutes have some sort of "supplement" then the nutes they have obviously aren't efficient enough to properly nourish your plant, that is just a way to get you to buy more of something you really shouldn't need.
2 things, All Purpose, and Blossom Booster. Perfect for cannabis. You spend alot less for a better product that is 100% organic, and your buying from a company that you know can be trusted.
