Help!! Rusty leaves with hot weather

Wondering why a bunch of leaves are turning like this and becoming crispy. It’s been really hot for a couple weeks. 95-105+ some days. Been watering heavily and feeding every other day. Purple kush, only happening on this plant. The other is fine and a different strain

thanks

You might be overfeeding the plants every other day, causeing a real acidic soil. Can you test the soils pH ?

I measure ph each feeding, 5.5-6, I could test the soil though too… thanks for the help
