When buds fail to open, there is either water stress, tiny insects at work, or bud infection. It may help to cut a bud in two and examine it closely for tiny insects. Viruses and fungi usually cause discoloration and/or distortion of the bud. Sometimes it helps to take an up-close photo and enlarge it so you can see more clearly. Since I don't know which plant is having problems, I'm afraid I can't provide specific advice.
