Is there a possibility that your plants have too much shade? That’s one thing that can interfere with flower productions; another thing is too much nitrogen fertilizer – work some bone meal into the soil (to increase phosphorous) and discontinue fertilizer. Another possibility would be aphids or thrips. These articles may give you some help: https://www.gardeningknowhow.com/ornamental/shrubs/butterfly-bush/butterfly-bush-care.htm ^[1]
