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

Nitrogen

Phosphorous

Potassium

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

Magnesium

Young stems and new leaves die

Calcium

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

Zinc

Leaf tissue appears yellow, while the veins remain green

Iron

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

Copper

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

Occasionally, the nutrients in a hydroponic system are used up faster than they can be replaced, and the plants will show a nutrient deficiency.  A quick fix for most of the deficiencies is to spray the leaves with an all-purpose, foliar fertilizer, although this will not completely solve the problem.  The best remedy is to change the nutrient solution every two weeks instead of every three weeks.  In some cases, it may be necessary to switch to a different type of hydroponic fertilizer, if the same deficiencies persist.
