What’s happening with my leaves?

All is good with your plant. You could guess that small calcium or light burn issues were happening, but generally - all better than at 99% of diaries. Prepare for chop ;)

I get this on my plants when there is too much or constant airflow in one area. The lower humidity could be a factor as well,but you want to be around that humidity late in flower. You could go up to around 50 percent.,and see if you have any fans blowing to much on any one area. if you notice it mostly on the tops of the plan nts it could be an indication of light or heat stress. She's looking pretty good I wouldn't worry too much about it. Good luck!

This kind of curling is usually indicator of light stress. But otherwise everything looks good. I am not sure you need to change anything. Let's see what more experienced growers say.
