Lol genetics. Oh you were in a car accident and broke both your legs and arms.
"Genetic failure...............throw it away, it will never be anything good."
40°C, the environment completely disrupts the plant's ability to uptake water and regulate transpiration. Rapid drying of the medium causes the salts left behind to concentrate, leading to dramatic EC spikes. When a plant is subjected to these massive osmotic swings, the root zone becomes highly toxic or throws essential nutrients out of balance. If the plant was perfectly healthy at germination, this collapse is unequivocally an environmental and cultural geographical issue rather than a genetic failure.
