Total of 10 tomato plants. Only two of them are exhibiting these symptoms. One worse than the other. Two varieties are heirloom tomatoes Mr. Stripey, and Black Prim. Other plants are fine. It has rained a lot recently. I am wondering if they have inadvertently gotten to much water, or if it Fusarium wilt with these two plants.

Please help. How much water do u give your tomato plants. I currently water 20 minutes with a soaker hose at 7pm. The plants do not get water if it rains the day before or if it is going to rain the next day.
