There is any number of good reasons why you might not get any smell. #1 reason is genetics some genes are just less smelly and better for stealth grows. #2 is phenotype some phenotypes are just less smelly. #3 is less terpene production because of nutrients or heat and light (heat and light can cause less smell) #4 is small plant small smell... And of course there is the spiritual reason - sometimes you can "pray to the plant" so it smells less... At least that's what some people say 😂! Hope this helps ! 🚀
