Leaves on tomato plants turning whitish color
A few of our tomato plants have leaves that are turning whitish colored. Does anyone have an idea what might be causing this? These plants were planted a week ago, in a virgin garden spot. The only amendments to the 20 X 40' garden area were 25 bags of Black Kow composted manure. There are 5 or 6 plants looking like this out of 28 tomato plants. They are all in the second row, which was planted about two weeks after the first row was planted. These affected plants were planted just prior to the low temperatures we experienced last weekend, lows of 40*. I'm not sure if this would have caused the leaves to turn white. Anyone have ideas on the cause or ideas on what to do to correct it? Thanks.
