What does it mean when the leafs mainly on top are curling up. The color is good and all the other plants are good. It is the tallest one so it's closer to the light.? Help please anyone

Yea it sounds like you need to move your light back, increase ventilation, lower temperature, or all three. Heat stress will make the leaves curl up into canoe shapes. If it's just the top leaves then moving the light back should do it.

I do see the curling mainly on top leafs of larger plants I have a light rail mover and just thought I would turn it off for aweek so mabey they could get more light. The temps are 75 and the humidity is 35 I have two osalating fans and an online 8 inch fan that's hooked directly to the 1000 watt light. The light sits about 24 in above the tallest plant and about 32 in from the smallest. Should that be fine? Sorry it's my first grow. Oh yea and the room is 10*10*9 ft.
