My photo was not good enough. The inflorescences are wilted, they are not hanging because are too big. Probably something with water. When do you know is time to stop watering the plant for seed collection?
André Arruda Sorry, but it depends on many factors. Landrace, mutant, compost type, fertilization, nutrient solution pH, E, microelements, time of watering (add when plants need water most of all), temperature, light, compost microbiota. It takes some time and efforts to optimize protocol for your conditions. Everybody had some troubles sometimes...
