Nutrient deficiency quick look table

Post by Nanook »

To use the table just match up the plants symptoms with those on the table. Nutrients that are shaded Red are the problem. Find that nutrient in the text below the table for the remedy.



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.

Very good, thanks Black. Handy to be able to just take a look at table and see what your issue is :)

Death. :oik!:

It's when tissue dies, you get dark bits of leaf and/or stem and it just dies off.

I think.

Start a thread with pics mate. Impossible to tell otherwise.

Yes necrosis is death :)

If you're in the Uk, they won't start flowering till September equinox. (assuming they're photoperiods)

As Nooky says, get some pics up and we can had a look.

They might just need some grub. :oik!:

Although you're joking Minty, that's a really good point. If you have a deficiency it's very rare that the lack of an element will be the issue. These charts are great for point of reference but actual issues are normally much more complex.
