The three amigos, and the lone wolf.
Steve teaches the foundation minerals the way you’d build a house: the slab goes down before anything goes in it.

Pour the foundation first
Steve calls calcium, boron and silicon the three amigos. They’re the concrete in the foundation, and everything else is built on it.
Change the recipe in the bag and ask yourself whether you’d build a house on that concrete. And time it: a fruit makes most of its cells early, in a window Steve puts at days in beans and weeks in tree crops, and that window doesn’t come back.

Earn the right
Potassium fills the house. It’s a big part of fruit size and quality, and it’s often the first thing on the order. Steve’s rule is to earn the right to use it: foundation first, then potassium.
“Earn the right to use potassium.”
