Do you have a grow journal documenting that? I'd like to see that. Especially the 1-3-2 performance.1-1-1 is ok in veg, but I've found that 3-1-2 produces better and more vigorous plants. 1-3-2 is best for flower
It may depend on the nutrients, but with what I use, 2-1-1.8 starts to approach N toxicity. I've seen Dyna-Gro users doing 3-1-2 and some of them look about the same. I don't believe I could do N=3 with what I use (based on what I've seen).
I finish at 1-2-1.8. I have yellowing if I get there too soon. 1-3-2 is (for me) booster level. I might do it once or twice. But, I don't notice any (significant) difference doing that or not. I'm a little nervous about recommending high PK levels because we see so many new growers with serious problems in flower because they think it's supposed to be done that way.
I believe hydro growers use higher ratios like that.
For @youngg , this is the latest veg photo using MiracleGro 1-1-1 ratio (day 27). When I say "pale" it's a very subtle matter of degrees. Please don't go crazy about your fertilizer being "inadequate." Hopefully your fertilizer will work as well and you can play with varying the ratios in a later grow. It's best to change it in small steps to see how your plants respond with your soil, your nutrients. (Not based on what someone else says.). Just get through this one without second-guessing things.
