I use the same throughout. The idea of a separate bloom and vege fertilizer is optimal is conjecture at best.
The most fertile lands on earth that produce some of the best grwoth don't magically change their NPK ratios when certain plants decide to flower. Now, that's not causation and not an argument... it leads to probabilistic assumptions, though. At the very least, it isn't needed for a healthy crop.
If you find a white paper with a suitable sample showing a clear benefit of one ratio of NPK to another, then go ahead and follow that good science's results... otherwise, it is a guess and more likely "bro-science."
If they labeled these things properly, it'd be based on molar ratio. The very fact they label it the way they do shows a total lack of undertanding, lol or simply catering to the public's understanding of things. that's kinda dumb, unfortunately, and all we get it that way, so it perpetuates a poor way of perceiving what is going on. You can do the math with a periodic table and that'll be better for comparing results than ppm or % by mass. It's about # of molecues, not grams.. Elements and molecues have different masses. 1 g of this is not the same # of molecules as 1 g of that.
