Hello everyone
Can anyone tell me what is wrong with my daughters tomato plants -- the leaves have turned yellowish and greyish and curling -- in fact they are dying and looking very poorly!!
Help please

The plants normally turn black if they're suffering with tomato blight, so it might be powdery mildew. As Mg says, a photo would help identify the problem.

Possibly blight but a photo would make i.d. and answer much better
