Cheryl, I really don't see pink on your blooms...I see brown discolorations. Have you been getting rain lately or winds?
When my grafted trees begin budding I bring them under patio cover to protect blooms from damage. There was one white that I had under the patio that had bloomed continuously for a couple of weeks, so thought it best to bring it back out into full sun again.
Well...the next two days it rained and it ruined the blossoms.
