That is generally a symptom of heat stress, try lowering the temps if you can.

Leaves curling
Hey Guys 👍🏻 I woke up today and saw the leaves of one of my babies all messed up. They are curling up and in, pointing to the center. PH is balanced. What could be the problem?

Anyone know what this is?
Hey so I have this auto flowering at the moment and I came back after a few days to see the buds are getting yellow tips and are pointing upwards, not quite sure what type of deficiency I’m dealing with but if you know would you kindly direct me in the right direction to fix it?

Light burn or nutrient issues? Female?
Does this look like light burn and maybe a lack of nutrients? Also can someone confirm that she’s a female or is it too early? I am first timer and think I see her lady parts already.

Kolas folding upwards?
Some of the tops of some colas are stretching up and not flat to allow the pistils to form correctly. almost looks as though they are stressed - I have had similar things happen with other tents and had to remove the plants in the end. How can I stop this?

Wind burn??
What else can cause the leaves to taco a bit like. Light burn. Just a couple here and there?? Could it be. Wind I've noticed I had a couple leaves claw a bit but only a couple there too and only on the leaves that was moving the most. ?

Leaves curl up and yellowing
Beginner question, as usual (first time growing anything in my life tbh). My 2 plants don't look too healthy, especially one of them. Leaves curl up and yellowing (or not, I am not sure). What am I missing? Thanks!

Slight lightburn?
First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape. 2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher? Other suggestions maybe?

Why have the leaves on my plant turned pale and crispy?
4 weeks into veg with auto and all of the leaves (including new growth) have turned very pale and dry, starting at the tips and receding rapidly. I’ve used the same two part nutrient solution in the same quantities as I did with the previous same auto, so Disease maybe?

Are my clones infected with HLVD virus? can this be reversed or should I throw everything in the trash?
I bought 12 clones from a grower, two grew slowly from the beginning. after transplanting, this "disease" appeared on two pieces, and now I think more have caught it.

Upward curling of leaves
One of my plants has started to have it's lower leaves curl upwards & started to go a yellow tint that's harder to see in my images. Yellow tint is starting higher up as well I think, but the curling is only on the low leaves. Is it nutrient defficiency, heat stress, wind stress?

The leaves are curled up, it's hot in the room these days, I guess this is the reason. Plants growing fast anyway, humidity between 48%57% but I'm worried because of this leaves problem. Should I ? I do my best to cool down but can I do something else ? Mist the leaves ? Thanks !
