I am kind of worried about my nutrient mix. Im useing AFF 5-2-2. I added 1tbl to one gallon of water. Ive read quite a bit that AFF is missing a lot of important nutrients. Now, i have many different kinds of nutrients in my shed, mostly chemical which I do not not want to use (20-20-20). I would like a good steady mix of nutrients that I know will be more than suffcient in supplying my plants with important nutes. I dont want to start adding a bunch of stuff to my mix, because I wont end up adding the right amount, and my next batch will deffintly be different. What is the NPK ration I should have during veg, and what should I have for Flower? What is the best balanced nutes to get for an outdoor grow, that is easy to supply to my plants? Some of my leaves int he middle of the plants have yellow blemishes in the middle, leading me to believe its nute burn.
