These numbers they give are just not guessed, but are based off of leaf samples, so follow the directions to start with. You may have to adjust, I need a touch more MgSO4.

These numbers represent the Masterblend directions and Hydrogardens Tomato Formula. Same stuff.
Yeah, what he said ! Most definitely
