Sulfur

What does it do?

One of the molecular building blocks for a number of proteins, hormones and vitamins.

What do you see?

Loss of general leaf color which may resemble a nitrogen deficiency. Strong purple coloration in the stems and petioles of leaves. The key difference to look for between a nitrogen and sulfur deficiency is where the chlorosis begins. Nitrogen chlorosis starts in older leaves. Sulfur deficiencies are first symptomatic in the youngest leaves.

What can you do?

Check your nutrient solution for a slightly acidic pH and raise if possible.  Foliar spray with Epsom salts at a rate of one tablespoon per gallon. We suggest Epsom salts, Langbeinite or Mineral Matrix.
