ppm x 2=lbs. per acre. Have you had a soil test and recommendations? If your soil is naturally high in some nutrients, you will want to balance the other nutrients to match.

For example, my soil is naturally very high in both P and K, so I don't add any in the spring. The only time I might add K is to finish a fruit in September. Also, the recommended Nitrogen was 75 lbs. per acre. I just figured what fraction of an acre I was growing on and applied calcium nitrate accordingly. If memory serves me correctly, calcium nitrate has an analysis of 15-0-0-19.5.

Don't forget the micro nutrients either. Balance them with your macros.
