Curling leaves - heat stress?
AZMamaBearstarted grow question 2 years ago
Some of the leaves are curling. Sits next to another indica that doesn’t seem to be affected. Temps here in Arizona have been 100-110 for weeks. I presume this is heat stress but would 💗 2nd opinion. She’s in the most protected area of the garden, so probably can’t fix this.

Oh yes heat stress. My sativa leaners are have the same problem. Have to try and shade her at the hottest part of the day.

Yep that is heat stress, You could try to put up some black pest mesh or even a screen so she does not get direct sun. Just make sure its only above so it does not restrict airflow. Black is better as it will absorb the sun instead of bouncing it.
Good luck and Happy Growing.

Oh, that's a definite.... You might try rigging up a little shade for her, especially during the hottest part of the day (like 11am - 2pm) - don't really know anything else you can do - maybe someone else has other suggestions... We're all having to deal with heat issues but yours sound particularly AWFUL....
Good luck!

Heat stress? (1st grow)Hi,
Here we start with the problems. The leaves are curling up (little yellow), not much. I've looked that up and it's probably heat stress?
-My led lamp is at 55 cm
-The plant receives 500 PPFD
Also a friend told me to water it nearly 1l, if that's the case I was giving way less

Leaf curling and mistingLeaves curling in one plant is worse than others.
Just noticed the leaves are curling worse on one plant, I think it's the one that had wierd genetics due to coming back from the dead early on
The soil was quite dry before watering today
How often should I be misting the plant

Leaves curlingI notice some leaf curling and also have some holes. Is it an issue? I raised the lights up a little as they were down below 20" i want to some defoliation but not sure where to start or if getting rid of big fan leaves and small leaves at the bottom will stunt growth

I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad
