This plant has actually torn itself. I know it was not me because the plant sits in the second row and I took it out to water with the rest of the plants and noticed a very tiny tear one day. At first I thought it was just the serrated part of the plant.

4 days later I take it out to water again and the tear is bigger.

I'm wondering if the light was a shock to the plant or if it's having heat issues even though the average temperature in my box is about 77-80 degrees with 35% humiidity.
