Anyone know why my cucumber plant leaves are turning white?

Report as

The reason your cucumber plants are turning white is that the soil is to rich in fertilizer, mainly nitrogen. Try digging up your plants, dig a large hole around where they were and fill it in with regular non-fertilized topsoil, then replant your cucumbers. They should soon start to thrive.

The whitening of cucumber leaves is caused by powdery mildew which is a fungal disease that becomes most severe during the late summer and fall planting seasons. Try growing varieties that are resistant to the fungal attack.
