I have a very beautiful calla lily plant which looks very healthy except that the flowers are not pure white but rather mainly green. The plant itself looks very lush and healthy but I am wondering what nutrient it is lacking to cause this problem.

Calla lilies' flowers normally start out green and will gain color as the flower ages. This is normal. Here is more info: https://www.gardeningknowhow.com/ornamental/bulbs/calla-lily/green-calla-lily-blooms.htm
