Some of my tomato plants have begun curling their leaves up. The first plant to start doing this now has almost all the leaves curled up. Some of the leaves are now yellowing slightly and have several small holes in them. The plants already have fruit that has progressed nicely up to this point. I have noticed a very few small ants and tiny flies but nothing I (in my limited experience) would call an infestation.
If anyone would like to tackle this one, I have a couple pictures I could email. Do I have a fungus, virus, infestation or water or nutrient problem?
