This is my first grow inside. Northern lights and blueberry. Autoflower. They look great but the leaves tips are curling. The were in my shed with no heat . It went down to 25 and moved them inside next day. Now they are at 70 degrees . Lights have been on 27/7.
Looks like heat stress
I’ve had them closed up. I took a panel of and have a fan on them now. Thanks
It’s not a bad case of it, so it should be fine.
Lookin good, good luck
