NITROGEN (N)
Pale plants, red stems, smaller growth. Rapid yellowing of lower leaves
progressing up the plant. Add any chemical fertilizer containing N. Treated
plants recover in about a week.
PHOSPHORUS (P)
Slow or stunted growth, red stems. Smaller leaves that are dark green.
Lower leaves yellow and die. Add chemical fertilizer containing P. Affected
leaves will not show recovery but new growth will apear normal.
POTASSIUM (K)
Affected plants are usually tallest and appear to be most vigorous.
Necrotic spots form on lower leaves. Red stems. Leaves appear pale or
yellow. Add chemical fertilizer containing K.
CALCIUM (Ca)
Lack of calcium in the soil results in the soil becoming too acid. This
leads to Mg or Fe deficiency or very slow stunted growth. Treat by foliar
feeding with one teaspoon of dolomatic lime per quart of water until
condition improves.
SULFER (S)
Plants suffering from S definciencies exhibit yellowing of new growth. Mix
one tablespoon of Epsom salts per gallon of water until condition improves.
MAGNESIUM (Mg)
Lower leaves yellow and may even turn white while veins remain dark green.
Blades die and curl upward.
IRON (Fe)
Leaves on growing shoots turn pale and veins remain dark green. pH
imbalances make iron insoluble. Foliar feed with chemical fertilizer
containing Fe or rusty water.
MANGANESE (Mn)
Necrotic and yellow spots form on top leaves. Mn deficiency occurs when
large amounts of Mg are present in the soil. Foliar feed with any chemical
fertilizer containing Mn.
BORON (B)
Growing shoots turn grey or die. Growing shoots appear burnt. Treat with
one teaspoon of Boric acid (sold as eyewash) per gallon of water.
MOLYBDENUM (Mb)
Yellowing of middle leaves. Foliar feed with chemical fertilizer
containing Mb.
ZINC (Zn)
White areas form at leaf tips and between veins. Occurs in alkaline soils.
Zn deficiency can be treated by burying galvanized nails in the soil.
Chemical fertilizer containing Zn can also be used.
OVER FERTILIZATION
Causes leaf tips to appear yellow or burnt. To correct soil should be
flushed with three gallons of water per one gallon of soil.
