I agree with mr sativa, aerated compost teas are great. If you are looking for a nutrient line, maybe earth juice, theirs is pretty good. However, you can make your own and better with the aerated teas. All sorts of things can go into it, and I think variety is better than just finding something that meets your npk needs. what I mean is, lets say you find some guano that was 6-2-5 or something and you wanted to use it for vedge, in my opinion adding more things adds to the diversity of vitamins, hormones and auxins. I like to use alfalfa meal, especially in vedge. it releases a lot of vitamins and amino acids as well as tricholine, a growth hormone for plants. Other things that are good are of course earth worm castings, guano (both bat and bird), mollasses, blood meal, kelp meal, cottonseed meal, fish emulsion, fish bone meal,superthrive, rock phosphate, etc. You can even start to tailor your ingredients on whether it will promote bacterial growth or fungal growth depending on if its for a vedging or blooming plant. And your flavor in the end, well thats all you..... a lot of times peoples strains all taste the same in part because they all use the same nutes, but you can bring out different elements of flavor and scent using organic nutes, and how you make your tea is like a flavor signature for your buds....
