Lower and Upper Leaf Symptoms (MOBILE NUTRIENTS) – Wrap up

Greetings,
I have listed below links to the posts that involve mobile elements. Mobile elements are more likely to exhibit visual deficiencies in the older leaves, because when these nutrients are limited they will be exported from the older leaves to the new growth. You will see the problems first on the lower leaves as the nutrients are moved to the newer fast growing leaves at the top of the plant.  So, when you see symptoms develop on lower leaves, read the posts for these nutrients and see if one is lacking.

Nitrogen

Phosphorus

Potassium

Magnesium

Zinc

The immobile elements tend to occur in new growth, since when they become limited, they will not be available to new growth. So, when you see symptoms develop on upper/new leaves, read the posts for these nutrients and see if one is lacking.

Manganese

Iron

Sulfur

Calcium


As always, E-mail me with any questions.
Good Growing,
Dr. E.R. Myers
