Symptoms of nutrient deficiencies in plants

This is a chart showing some common symptoms of nutrient deficiency and over fertilization. Always remember that you never want to over compensate for any deficiency because of the risk of over fertilization. Use caution when adjusting the strength of the nutrient solution. Deficiencies may also be attributed to a solution is too acidic or too alkaline so pay close attention to your pH. In order for all elements to be readily available to the plant the pH should stay in the range of 6.5.
