Tomato Pests & Diseases

Leaf discoloration

11 years ago

I have two tomato plants in a self watering container. Lately, there has been some discoloration of the leaves. Does anyone know what this is and what I can do about it? Will it affect the fruit? (Disregard the "dust" on the leaves - that's from some wood work that was done on my deck). Thanks!

4 possibilities - choose the one that seems most likely.

Temperature fluctuations - temperature dips below 50 degrees.

Phosphorus deficiency - can remedy with fertilizer or epsom salts. The epsom salts are magnesium, but they help the tomato absorb phosphorus.

Curly top virus - is is common where you live? It is spread by leafhoppers.

Psyllids - These are very small insects, so look closely to detect them. If you see them, google tomato psyllid ipm. IPM means intergated pest management, and that will give you various means of pest control, beginning with what is least harmful to the environment.
