My lady plant is missing clothes! Is this normal?

Hey all,
This is a unique grow.
Almost every large leaf has either fallen or been trimmed off manually. I am within a week of harvest and all I have are the smaller sugar leaves and a few mid sized fans.
Buds look great though.

No doubt some of this is normal behavior, but I am curious to hear from you and your experiences. How common is this?
There was a deficiency late in flower, we believe either calcium or magnesium and we corrected that issue. Outside of that, the plants grew healthy from birth to harvest using quality soils and nutrients. I even check PH, PPM, regulate temperature, RH...

Thoughts?

If all of the leaves fell off, or had to be removed due to damage it is not normal. A plant can get to the finish line with a thick healthy set of leaves. The deficiency you mention is the likely cause. But without pictures nobody can really tell you for sure.

Good luck on your next one!
