some of my tomatoes and cucumbers have it but have tomatoes and cucumbers on them, should I just leave them, cut the tops off of the tomatoes(only the top of the plants is affectted) or pull them out! also my grape vine and a shrub next to it seems to have it too even though there no where near the tomatoes and cucs, what can I do about them!

I am having a similar problem with tomatoes & was told it could be magnesium deficiency, and to apply magnesium sulphate. Quoted "with magnesium deficiency large areas of leaf become necrotic. A further feature distinguishing magnesium deficiency from other disorders is that the symptoms do not usually appear in the field until mid to late season".

Its a new one to me too, try some tomatoe fert which will have all the balanced nutrients to make your plants grow well.
