Corn grew at a tremendous clip last week.30C temperatures and good soil moisture conditions made things pop.During this fast spurt of growth
some hybrids had difficulty unfurling their leaves properly. Hybrids that are more prone to having their leaves remain wrapped

during such fast growth expressed whats termed " yellow leaf. " When leaves don't unfurl properly they receive insufficient sunlight to produce their necessary chlorophyll.When these leaves unfurl they will appear yellow for 1 -2 days.There is no worry with such a phenomema as once the leaves do unfurl and they receive sunlight they will produce their chorophyll and turn dark green.I will admit though that it can be an unsettling sight for first time growers experiencing this phenomena.
