Symptoms
Young tissue is mostly affected by Ca deficiency. New emerging leaves are small, deformed, yellow and subsequently necrotic. Slightly older leaves show marginal and interveinal chlorosis. Necrotic spots may appear within the chlorotic area.
With severe deficiency, flower buds and shoot tips die off, shoot growth is completely inhibited.
Calcium undersupply of the fruit is the reason for 'Blossom End Rot', i.e. browning and decay of the fruit tip.
Reasons
Calcium deficiency.
Ca undersupply might be induced by nutrient lockout due to excessive N or K., or resulting from low transpiration.
Chili - Chlorosis

Calcium deficiency made worse by
Acidic soils
Sandy or light soils (leaching)
Acid peat soils
Soils rich in sodium
Soils rich in aluminium
Drought conditions
Fruit high in nitrogen or potassium
Large fruit
Calcium is important for
Strong cell wall formation and thus for plant and fruit integrity
Fruit development, fruit quality
Prevention of Blossom End Rot, a physiological disorder, and promotion of plant health
Yara recommended fertilizers for Calcium
YaraLiva™ NITRABOR™
Chili:
Apply 5-10 grams per hill 3 days after transplanting. Repeat application every 7 days thereafter.
