m0useanswered grow question 4y ago Everything your doing seems on track for a successful grow.
My one friend likes to dry his bud between 13c-15c (55.4F-59F) says the terps stay intact.
I have dried mine at temps like yours, and I find the smell comes out in the cure, also if you break a nug open it should come out.
But there is the chance a Pheno is at fault, sometimes they are not as fragrant or frosty as there siblings. no fault of the grower just genetics expressing themselves.
Cheers
