Brassavola nodosa in bloom but without fragrance

[sweta]

Hi,

My brassavola nodosa that I bought a year back is in bloom. It bloomed about 3 weeks ago. I just got back from a trip out of country and havent noticed any fragrance in the night. From what I've heard the fragrance should be strong but couldnt smell anything. I'm not able to figure out the issue and feel disappointed🥺 I live in seattle area, house temperatures is at 73F. Usually watered once every week but couldnt water it for last 3 weeks when I was gone out of country. Fertilized once in 2 weeks. I'm attaching pictures of the blooms. Its grown in large chunky pine bark with some sphagnum moss. Added the moss so it can withstand being without water while I was gone.
Oh and its also grown under grow lights.

Thanks,
Sweta
