Leaf curl

[maslor57]

I have some leaf curl like a taco on my bubba kush plants.

They seem quite happy other than this.

Is it from heat stress? We've had some warm days but the temp has never gone over 85, it usually hovers around 79.

Did I have my lights too close?

They are sharing space with two Cheese plants that show no signs of curl

Thanks

This does look like the lights were too close to the plant. I have seen similar leaf curl when my lights were too close. Was this plant closer to the light than the other two?
