Terra Aquatica vs GH feedchart

Hi I am running my first dwc with terra aquatica nutes tripart micro grow and bloom. TA are the same nutes as GH (same NPK ratios) and I am confused about feedcharts. TA in veg says I should use:
Grow 1.8 ml/l
Micro 1.2 ml/l
Bloom 0.6ml/l
The ratio is 3:2:1 (grow:micro:bloom)
GH feedcharts says in late veg I should use:
Grow 5,6 ml/gal (1,5ml/l)
Micro 6,0 ml/gal (1,6ml/l)
Bloom 4,2 ml/gal (1,1 ml/l)
The ratio is 1,35 :1,45 : 1

Why the ratios are totally different if they have same NPK? Which feedchart should I stick to?

Either works fine

GH changed their feed chart a few years ago; it was previously the 3:2:1 ratio for veg and 1:2:3 ratio for flowering (same as the TA nutes).

Here's the veg nute profile for both, they're both quite similar and both will grow healthy plants.

* For the TA recipe, it's using 6-4-2 ml/G. The absolute elemental ppms aren't terribly important in this context, it's the relative ratios that matter most in comparing the two.

That makes a sense. Thank you very much
