Leaves pointing up under sunlight, but nothing under my light which is MarsHydroTS600(100w) like 2feet above. So that means its not strong enough? If i put it closer it wont help right? Thanks a lot!
the sun vs grow lights is not a good comparison. the suns spectrum and power are massive.
Use you lights manual and try and find suggest hang height and dimmer levels if it has any.
