lol he said droop, yes water temp can be an issue as it can cause a stress, are you in soil? are you letting them dry out fully before wateringWhat do you mean your leaves drop? Like they turn yellow and they rip off or what? Or they just drop while they full green?! What do you mean it doesn't harm the plant. The plant needs the leaves for nutrients processing also light and CO2. It harms the plant in any way. Sounds like your plant is dead....
