||Micronutrient. Important for phloem transport and cell elongation. Aids production of sugars. Essential for fruit & seed development.
||Growing tips become deformed or die, also leaf discolouration.
||Leaf tips yellow & die. Leaves look scorched & fall.
||Secondary macronutrient. Many functions including structural integrity of cells & growing tips.
||Reduced growth, deformation or death of growing tips. Poor fruit development.
||May cause deficiency in either magnesium or potassium.
||From CO2 in air, essential to build sugars.
||Micronutrient. Important in fluid balance & in breaking down water for photosynthesis.
||Club roots. Wilted leaves becoming bronze, chlorotic then dying.
||Salt injury causing leaf burn.
||Micronutrient. Transition metal. Important in electron transport & reproductive growth. Aids in root metabolism and helps in the utilization of proteins.
||Similar to Iron deficiency if soil acidic.
||May cause distortion of new growth. Can occur in peat potting composts.
||From H2O, essential to build sugars.
||Micronutrient. Transition metal. Important for enzyme synthesis & function. Electron transfer processes and chlorophyll synthesis.
||Chlorosis. Yellow/white interveinal areas on young upper leaves leading to areas of leaf death.
||May cause leaf bronzing with tiny brown spots.
||Secondary macronutrient. This is an essential part of the chlorophyll molecule. Vital in photosynthesis and respiration.
||Chlorosis, leaves appearing pale green or yellow. Yellowing between leaf veins spreading to younger leaves. poor fruit development and low yield.
||Excess rare as well tolerated. Too much will suppress Calcium & Potassium & reduce growth.
||Micronutrient. Essential in photosynthesis & respiration including enzyme systems breakdown of carbohydrates
||nterveinal Chlorosis, yellowing or mottled young upper leaves. followed by brown spots giving a chequered red effect.
||Reduced growth. Older leaves with brown spots surrounded by a chlorotic ring. Looks like Iron deficiency. Can occur in acid soils.
||Micronutrient. Essential component of enzymes for nitrogen fixing.
||Interveinal Chlorosis on older leaves which may distort.
||Micronutrient. Found in seeds and fruit. Needed to help form urease to break down urea nitrogen for plant use. Involved in the iron uptake from the soil.
||Decreased iron utilization.
||Chlorosis and necrotic leaf margins.
||Primary macronutrient. Needed for photosynthesis, growth & respiration. It is a constituent of DNA, RNA & amino acids which are used to build protein molecules. Nitrogen is inert & has to be incorporated into the plant by nitrogen-fixing bacteria in their root nodes.
||Pale & lower leaves yellow or dying. Light green to yellow appearance of leaves, especially older leaves; stunted growth poor fruit development.
||Dark green over vigorous foliage which is susceptible to disease & insect attack & will not overwinter well. Poor fruit & seeds.
||O2, H2O. Essential for photosynthesis of sugar molecules.
||Primary macronutrient. Essential for reproduction & photosynthesis & involved in energy transfer & formation of oils, sugars & starches. Helps maturation, blooming & root growth.
||Slow development, poor growth, flowering and fruiting. Leaves may appear purple.
||May cause micronutrient deficiencies, especially iron or zinc.
||Primary Macronutrient. Activates many enzymes, encourages flowering & important in osmosis (fluid balance). Second to nitrogen in absorption for most plants. Builds disease resistance, improves fruit quality.
||Older leaves yellowing around edges & then dying. Poor growth & vulnerable to disease. In Passiflora few or no flowers & poor fruiting & poor heat tolerance.
||May cause deficiencies of calcium & magnesium.
||Secondary macronutrient. Constituent of some amino acids. Enzyme cofactor and constituent. Improves root growth & seed production. Electron transfer processes and chlorophyll synthesis. Cold resistance.
||Yellowing of young upper leaves spreading to whole plant. Occurs on new growth initially.
||May cause early leaf drop.
||Micronutrient. Enzyme cofactor, growth hormone synthesis. Transformation of carbohydrates & sugar consumption.
||Interveinal chlorosis/yellowing on young leaves, reduced leaf size. Rosetting.
||May cause iron deficiency.
