Guide to Nutrient Deficiencies in Your Vegetable Garden

Some nutrients are major…some are just very important…and the lack of any of them can ruin your crops.


Most gardeners are familiar with the "N-P-K" in commercial fertilizers: nitrogen (N), phosphorus (P) and potassium (K). But these three represent only half the major nutrients a plant requires in relatively large amounts. The other major nutrients are sulfur, calcium and magnesium. Consistent use of Perfect Balance fertilizer will result in the proper calcium/magnesium ratio for your soil, as well as provide the necessary nutrients which are not in balance.


Minor nutrients are not really minor, or unimportant. They are essential – vital to plant growth but needed in lesser amounts than major nutrients. Essential minor nutrients are the secret weapons of successful gardeners and farmers. In spite of their critical importance, most fertilizers do not include them. Our all-natural Perfect Balance Custom Fertilizer restores five minor nutrients to effective levels.

Plants, like people, can suffer from too much of a good thing. In humans, vitamin D, necessary for health, can cause disease or even death when too much is consumed. Similarly, too much boron can be toxic to a plant. Our lab analysis of your soil tells us which micronutrients are already abundant, and which ones your soil needs to achieve perfect balance.

Blossom-end rot

Calcuim Deficiency in Corn Leafs


Calcium is needed for cell division and plant growth. Its buffering characteristics are critical to soil balance and largely determine the availability of other nutrients. Lack of calcium results in yellow or pale leaves, and causes blossom-end rot on tomatoes and peppers. A deficiency in beans causes yellow leaves with curling margins, stunted plants, and blackened, dying shoot tips. Deficiency causes brown-tipped leaves on cabbage, forked roots in beets, and unusually small potatoes.
