Answer: It sure sounds like thrips to me. To find out for sure, call your county agricultural extension office (ph# 715/634-4839) and ask if you can send some of the affected plant parts to them for diagnosis.
If thrips are the problem be prepared next season to spray the plants with pyrethrin or neem (an organic control - extract of the neem tree seed). Apply as directed by the product label - you may need to start spraying even before the buds appear. Best of luck!
