Give them some time. My current strain has no fragrance in the first 3 weeks then gets a very floral strong perfume (like roses) then eventually goes very piney and super stinky late in the game. The
terpenes develop over time in my experience. Some even stink in veg though.....highly strain dependent.
Sometimes when I am cleaning up the lower branches trimming out larf I'll crush some of the leaves and this can sometimes give me a preview of the smells that are coming along......
