Curled leaf problem - what is it?
One of my tomato plants has developed strange curly leaves. All the rest look normal and I have many plants. I took this picture a couple of days ago when I first noticed the problem. The tomatoes have only been in the basement under lights - not outdoors yet. They are all in the same seed starting mix and all have been watered the same to the best of my ability. I haven't noticed any kind of insects on any of my plants. The seeds were started on April 10th. Any help much appreciated - TIA
