Time of feeding

Hi girl! My cannabis girls are only in hydro but I have grown chilies in soil. I did not think about the time of the day when I gave water to them, I only did it when I had the time to it etc. There might be some science that maybe first thing in the morning some fresh water and nutes would be good so the plant has all day to use that fresh stuff, but this is just speculation on my behalf :D You just need to kinda "feel" when they need it. It all depends on your style also but you don't need to water the girls during the night unless you forgot and they are drooping. Plants don't photosynthesize during the night but they transpire and I believe that they won't drink through the roots during the night.
