Hello. I am growing Banana Cush Autos under HLG Quantum boards. I have been experimenting with light height and brightness and had some leaf curling (down). I have made adjustments and I think they are happier. Question: will the leaves that curled under straighten out some, or, should I look to new leaves for further symptoms?
I always watch the new growth…
it depends on how badly they curled.
Tips curled under and looked, “skinny,” but didn’t have burnt tips. I look in every couple hours to see how things are. I will watch the new leafs forming. These new quantum led lights are awesome but require a whole different approach to height and brightness over the blurple lights.
If you noticed it after lowering the lights, then that is probably the problem.
However leaf curl can be so many things. Maybe fill out a support ticket and post here so some of our experts can help:

Answer to my question. After raising the height of my lights and dimming them a little bit that the plants responded and the leaves are indeed un-curling and repairing themselves. Thank you for your responses.
