Hi buddy!
It seems that the signs presented by the plant are due to a calcium deficiency.
Some of the reasons for which this may be the case:
-Low levels of calcium in the irrigation water
-Excess phosphorus or potassium (blocks assimilation of calcium and other nutrients)
If you are not over-fertilizing with phosphorus or potassium, try using a product such as 'Calmag'.
Also consider doing a root flush. It is advisable to do this at least 1 week before the harvest.
Sweet smokes,

We've been struggling with some deficiencies with one of our two Dark Devil's lately as well.
They were both total magnesium hogs early on but we let our soil ppm's get way out of control before we caught it and now facing phosphorus deficiency, most likely due to lockout.
Hope you get yours figured out. They look really good otherwise.
Best Wishes!
@VanCplGrows, yes she was a mag hog and now I’m pretty sure she’s going through lockout! Only a few weeks from harvest so I’ll do one final feeding then flush for 10 days. I’ll know better next run
