That's kinda funny thirstygrower..dehydration. Some people do that on purpose towards end of flower, more so last week before chop. especially if their drying environment is more humid than ideal. . maybe not a 1.5 weeks dry back though. but you are fine,the damage is done,you can only learn. Leaves are really important at any stage. Buds can photosynthesis some too but not going to produce its best under those conditions. At least they are still alive. it is not ideal, and you may have lost some yield, but better than nothing. but the buds look really frosty and nice still. I'm sure they are gonna take a slight quality hit too but plant is going to want to use up the nutrients in the leaves anyway as it dies.
