Pictured here is the new growth of one of my tomato plants. The variety is "de Berao". The plant has grown normally till about 6 ft. high and then grew on like this. I'm not sure if I should call it a problem as the plant shows no other illness so far. But I'm sure it isn't right either. The deformed vines are considerably thinner than the healthy parts further down. The leaves don't unfold and stay really small and fat. This has been going on for about three weeks now and only this one plant is affected. All nearby plants stay healthy. Are there any tomato experts among us pumpkin growers who can comment on this? Monty? Tomato Grower? Please also note the next image.
