Thanks for taking the time to reply! This is exactly the brain work I need to do. Without leaf diagnosis or whatever fancy methods there are, a/b-ing and then referring back to the calculator makes sense. Another thing I never stopped to realize was that the addition of Armour SI might be throwing off my Potassium ratio -- specially since i have heard people say Jacks is considered High in P! I should compare the numbers between Jacks 3-2 or 3-2-1 and GH aggressive Veg three part 3-2-1 grow micro bloom respectively. This is very good advice, thanks agin!

Jacks is not high in p it has 50ppms of p. Go to greengenesgarden on Instagram and in his story highlights is a nutrient section, and he has docs already up comparing most dry powders! He lists them and the ppms as said on the label
