The roots in the 2 week picture look good, but they look like they are turning brown in the 3 week picture. Also I see algae growing in the vertical tube on the left. My plants continued to grow in 80-90 degree
nutrient temps also, just not healthy. The attached picture shows the damage done by prolonged exposure to high nutrient temperatures of my strawberry's. I added Ice twice a day, but the consent fluctuation of nutrient temps still took their tole.
