Exclamation Guide for diagnosing plant problems...A Must Read!!
permalink
I came across this neat little list that can probably help a lot of people out. If you like it check my post in the General area...I need some help!

Quick Deficiency Guide

Nitrogen: Entire plant is light green in color; lower leaves are yellow; growth is stunted....

Phosphorous: Entire plant is bluish-green, often developing a red or purpleish cast; lower leaves may be yellow, drying to a greenish-brown to black color; growth may be stunted...

Potassium: Leaves have a papery appearance; dead areas along the edges of leaves; growth is stunted...

Magnesium: Lower leaves turn yellow along the tips and margin and between the veins; the lower leaves wilt...

Calcium: Young stems and new leaves die...

Zinc: Leaf tissue between the veins is lighter in color; yellowed; papery in appearance...

Iron: Leaf tissue appears yellow, while the veins remain green...

Copper: Leaf edges appear dark green or blue; leaf edges curl upward; young leaves permanently wilt...

Sulfur: Young leaves turn pale green, while the older leaves remain green; plant is stunted and spindly...

Mananese: Growth is stunted; lower leaves have a checkered pattern of yellow and green...

Molybdenum: Leaves are stunted, pale green, and malformed...

Boron: Young leaves are scorched at tips and margins...
