Please Help (new issue in flower stage)

These are the two lambs breads that I have been working on. These leaves started curling. I am mediately reduced the light thinking that it is heat stress. They are getting plenty of water. I have given them a calcium treatment about a week ago. I water daily about a liter each. Does anybody know what is going on here?.

Pictures with white light? Can’t see anything in purple. Medium? Water pH? PPM?

I’d agree with your first thought. The ‘taco leaves’ is usually heat related. How close are they to the light? They look tall.
