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

What are my leaves telling me?
Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

The edges of the leaves are curling up. I suspect the light is too strong. I've now turned the light back down to 40%. The PPFD value is now back to 150; it was almost 250 at 50%.

Weird Leaf Problem
New leaves show strange twisting/curling. Humidity ~50%, temps 28-21°C (D-N). Did LST last week—could twisting be due to reorienting to light? Using All-Mix soil, Bio Grow, Calmag. Water left 24h, not pH'd. Some leaf holes caused by me. Flipping soon—help resolve this issue!

Hojas en formas de canoa
I have canoe-shaped leaves in the 3rd week, just the lower leaves, I'm not fertilizing yet. I have LED light so it's not heat. I suspect something related to humidity or pH. Any experience?

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 !

Curly leaf edges
I'm getting some serrated, curled up leaf edges. This doesn't really bother me cause it happens very often, just curious as to what the cause could be. Maybe the LEDs are too close? It's 160w of white COBS at around 40 cm distance

One of three plants curled its leaves.
One of these three seeds seems to have suffered a bit, but unsure why - the conditions have been pretty much identical from what I can tell. The first set of leaves curled quite significantly but the new growth seems to be ok? Any ideas?

Any idea why my top leaves would be taco'ing at the edges? I keep my room about 72-73 degrees and am just using one CFL bulb (45w) that I keep at least 6 inches above the plant. And I keep a gentle fan or two on her most of the time to keep the air moving. Thanks.
