Low humidity, dry heat, it is hotter. Must be watering your garden a lot. Some years it was so hot that my fruit trees leaves just turned brown.Dry heat. The humidity in there that day was 8%.
It appears to be fine. It might be sulking since I cut the top off.
Your mango tree sound so funny, sulking. I am sure it is ok, it will find way to grow horizontally. We trim our like your too so it goes not grow so tall.
