Tomato Leaf problem

Posted 537 days ago

My problem is black spots on the lower leaves of my tomato plants when they are green. Even when small seedlings only 65mm tall. The leaves then go progressively yellow and and eventually wilt. Is this a soil problem, say lack of nitrogen? Is it over watering? Or is it a disease? I am using dynamic lifter as a fertilizer plus the occasional dose of Thrive. It has been fairly cold in the mornings over the past 4 weeks. Could it just be the cold weather? All the tomatoes are of various varieties not just one type. Would appreciate some help.

Hello, I was listening to a garden show on ABC radio yesterday morning and they talked about a problem where lttle white flies get on the tomato plants and eat the goodness out of them. They recommended to spray with pest oil. Don't know if this is your problem, but maybe have a little look for little white flies. Sarah.

Hi Sarah,

Thanks for the post. I did experience the white flies about a month ago. But as they are now long gone I don't believe that this is my problem. Someone has suggested that the problem is a bacteria. Ken

Hey Pomolo,

Thanks for the link. It is bacterial speck. The photo shows exactly what I am getting. Seems that the constant rain on the leaves has created the problem. Bought some copper spray so I will see how I go.
