Advanced nutrients measurment?

This maybe a silly question but I bought advanced nutrients sense grow part a and b. And when I read the instructions what to mix in water it says add 2 ml per litre for small plants, would that mean I put in 2 ml of both part a and b into a litre of water. Or would I put 1 ml of each making 2ml all together?

2 ml each. Idk about the sensi, but the other AN lines runs really strong. I was at 1ml/L of the Connoisseur A&B in early veg and it was strong. I never got over 2.5ml/L in full flower without burn.

2ml each but legit half strength it always. Never had a single nutrient not burn a plant at full strength. Star at half and work your way up.
