I started out with 3-2-1 all the way thru the grow cycle and I didn't like the results. Now I change the NPK balance when transitioning and then in full flower and again towards the end. The results weren't bad, total weight was in normal range but overall the nug size wasn't what I usually get. After changing to a higher PK in flower they went back to really producing not only weight wise but the nugs are swelling up really nicely and better than any run before.
Below is how I currently mix my ratios including the math I used to get them where they should be:
