Beginning September: entire week with temperatures >36°C (23°C at night) and sunny days, no really humidity.
Daylight 12h43 : 7h37/20h20 (-2 min)
Ventilation 24h/24 in the greenhouse

- Ventilation ok.
- I added some FishMix to correct an hypothetical nitrogen deficiency

- heat or exposure are not the problem
