Blueberry auto flower leaf concern

I have a blueberry auto flower with about a week left before harvest. The top leaves have started to have issues (see picture). It started a week after I did the flush. It is grown indoors in a closet with temps at 82 and humidity around 45%. The light is a Mars Hydro 100 watt led approximately 16 inches away. I don’t think this is going to be an issue because the harvest is right around the corner, but I would like to know what it is in case I experience it again in the future. Any advice will be greatly appreciated. This plant has grow great, and up to this point there have been no other issues.

If you’re close to harvest then there’s no need to worry. She’s just feeding off of herself.
