1. Nutrient Deficiencies and Toxicities

2. Nitrogen Deficiency on Chrysanthemum Uniform chlorosis of lower leaves turning to necrosis; stunting; chlorosis progressing up the plant

3. Nitrogen Deficiency on Turf Grass Nitrogen deficiency and toxicity and same turfgrass area due to the improper application of fertilizer.

4. Phosphorus Deficiency on Chrysanthemum After turning a deep green, lower leaves become chlorotic and then necrotic

5. Phosphorus Deficiency in Rose Leaves are generally stunted and may be gray- green

6. Potassium Deficiency in Rose Tip and marginal yellowing, browning and necrosis of older leaves.

7. Calcium Deficiency on Chrysanthemum Top leaves turn chlorotic in pattern and are incompletely formed (many tend to appear stripped like).

8. Calcium Deficiency in Roses Leaves become dull gray-green and bend down at margins, and edges later turn yellow and brown

9. Manganese Deficiency in Chrysanthemums Interveinal chlorsis starting at the top and progressing downward

10. Manganese Deficiency in Roses Interveinal chlorsis becomes necrotic

11. Magnesium Deficiency in Chrysanthemum Interveinal chlorosis of lower leaves

12. Iron Deficiency in Turfgrass Interveinal chlorosis caused by iron deficiency

13. Iron deficiency in Chrysanthemum Interveinal chlorosis starting at the top and progressing downwards

14. Iron Deficiency in Gardenia Foliar chlorosis on leaves of Gardenia

15. Iron Deficiency in Rhododendron Iron Chlorosis

16. Iron Deficiency on Roses Interveinal chlorosis in which main veins remain green

17. Copper Deficiency in Aglaonema Stunted and deformed new leaves

18. Molybdenum Deficiency in Poinsettia Leaf edge chlorosis and scorch

19. Molybdenum Deficiency in Chrysanthemum Blanched upper leaves

20. Fluoride Toxicity in Dracaena Fluoride toxicity in Dracaena with leaf damage

21. Fluoride Toxicity on Dracaena Severe Marginal Necrosis

22. Fluoride Toxicity in Dracaena Slight symptoms of fluoride toxicity grown under interiorscape conditions

23. Fluoride Toxicity in Calathea Marginal chlorosis and necrosis developing within 1-2 weeks of treatment of soil drench of sodium fluoride

24. Fluoride Toxicity in Aglaonema Chlorotic and necrotic lesions

25. Salt Toxicity in Roses Marginal necrosis of leaves

26. Salt Toxicity in Geraniums Leaf edge necrosis caused by excessive levels of soluble salts in the growing medium

27. Salt Toxicity in Geraniums Wilted Geranium caused by root injury from an excessive levels of soluble salts in the growing mix

28. Salt Toxicity in Impatiens Defoliation resulting from excessive soluble salts
