I planted several deep purple wave petunias. The flowers of those planted in one particular area turned white practially overnight. The others planted in different areas are fine. What could the problem be?

Soil pH might turn the flowers white but the problem is usually associated with strong reflected heat and light. I'd just pinch off the flowers and hope the rest maintain the right color. A soil test will tell you whether the pH is in the normal range for petunias (6.0 to 6.8)
