Isn't the NPK too low for AN sensi grow

am I suppose to add more additives. sensi grow ph perfect part A and B NPK values are very low.. Part b: 3-0-0 Part A: 1-2-6. That's so damn low. in veg right now..

Heavy 16 is very similar... combined Sensi is 4-2-6 and combined H16 is 5-2-6. The ratio is all that matters (2-1-3 is fine)... the dilution just means that they're ripping you off by making you add more. Like, the only difference between a 2-1-3 nute and a 6-3-9 nute is that you'll need to use three times more of the 2-1-3 (generally speaking for base nutes).
