Copper deficiency-Lettuce

Simptomi
Plants seem to be wilted and flabby. Along leaf tips and margins chlorotic mottling arises, which proceeds from old to younger leaves. Grey-brown necrotic areas develop in the chlorotic zones. Starting on the tips, leaves turn yellow and fade. Sometimes veins show light red or pink discoloration. Furthermore copper deficiency leads to inhibited growth and small, light heads.
