Over Fert. |
|
|
N - 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.

|
|
P - 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 appear normal.
<< Back to Chart | Read more about Phosphorus (P) >>
|
|
K - 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.
<< Back to Chart | Read more about Potassium (K) >>
|
|
Ca - 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.
<< Back to Chart | Read more about Calcium (C) >>
|
|
S - SULFER (S )
Plants suffering from S deficiencies exhibit yellowing of new growth. Mix one tablespoon of Epsom salts per gallon of water until condition improves.
<< Back to Chart | Read more about Sulfer (S) >>
|
|
Mg - MAGNESIUM (Mg)
Lower leaves yellow and may even turn white while veins remain dark green. Blades die and curl upward.
<< Back to Chart | Read more about Magnesium (Mg) >>
|
|
Fe - 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.
<< Back to Chart | Read more about Iron (Fe) >>
|
|
Mn - 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.
<< Back to Chart | Read more about Manganese (Mn) >>
|
|
B - 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.
<< Back to Chart | Read more about Boron (B) >>
|
|
Mb - MOLYBDENUM (Mb)
Yellowing of middle leaves. Foliar feed with chemical fertilizer containing Mb.
<< Back to Chart | Read more about Molybdenum (Mb) >>
|
|
Zn - 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.
<< Back to Chart | Read more about Zinc (Zn) >>
|
|
Cu - COPPER (Cu) Fungicide, sulfate [Cocus] Apply foliar.
<< Back to Chart | Read more about Copper (Cu) >>
|
|
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.
