Many people only have small containers in which they are trying to grow vegetables, and they only need small amounts of Pre-Plant and Weekly Feed Mixes.
Here’s how to mix Weekly Feed using one tenth of a 10 ounce Micro-Nutrient packet:
Mix 2.5 pounds of 16-16-16 or similar NPK mix with
6 ounces of Epsom Salt, and
1 ounce of Mittleider Magic Micro-Mix
For similar amounts of the simple Pre-Plant Mix:
Mix 2.5 pounds of lime (gypsum for less than 20″ of annual rainfall)
2 ounces of Epsom Salt, and
1/2 ounce of 20 Mule Team Borax
Apply Pre-Plant 1 ounce per running foot and mix with the soil before planting.
Apply Weekly Feed 1/2 ounce per runnning foot and mix with the soil before planting. Thereafter, after plants are up, feed 1/2 ounce weekly until 3 weeks before maturity.
