I mix 5 gallon buckets for fertilizer and pour directly into the earthboxe's. I had the ber early so I added lime in those to boxes and they finished the rest of the season ber less. My reason was the cost was minimal for a lot of fertilizer.

You should use CaNO3 in equal amounts with the 4-18-38, this will ensure that you get no BER if your watering is good. You should also use MgSO4 at half the amounts as the other two components.
