During the night, I have noticed that 2 plants out of 3 stand with normal leaves straight, while 1 has leaves going down during the darkness and when the sun rises, it gets back to normal.
They are all same strain, grown in same way, why?
Hello. As with babies, each seed is a induvial and is slightly different than the others. When this plant sleeps it likes to do it with it's leaves down where as the others can sleep with their leaves up. Chuck.
This is normal and nothing to worry about... each plant can react to the same set of conditions differently than the others - goes for nutes, too... you might find one plant over-reacting to the same nutes that others in the same grow love...
Good luck!
