hey man looks like heat stress leading to some other problems, keep the root zone cool by insulating it with some white cloth and watering with colder water. get as many fans as possibly pointing to the root zone, but the best thing to do is to get an "evaporative cooler", it's pretty cheap and it will work for your conditions hopefully reducing the temps to 25°C . Everything else looks fine but if you dont fix this soon your buds will be airy! hope this helps ! 🚀
