I noticed some leaf curls on 6s head. That is 2 cm to the lights and in the middle. I attached thermometers clip there and saw 34C degree. So, I added a pc fan and it dropped highest value to 29C degree. This was a late move but better than nothing I think.

Here are the shots. You know the order already.

Edit: Yes, afternoon there was sun and 13 dropped top leaves down again.
