Usually a sign of over heating or lack of air movement. However, I have seen the odd plant grow like this for absolutely no reason over the last 40 years.

Leaves are curling up
The sugar leaves on one of my plants have curled up, I was wondering if this could be a humidity issue or maybe a temperature problem. Can this affect the plants yield as it is approaching harvest time.

leaves dry and curling up
Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches

Is there enough light?
If the upper leaves start to curl upward slightly into a âtacoâ shape, does that mean the light level is already at the upper limit and I definitely shouldnât increase it?

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?

Hi all, Are the leaves point upwards a good sign of a happy plant or a sign of too much light? This is my first grow and i am trying a variety of setups and just trying to be cautious as what I have read in the forums is either one way or the other. Thanks!

Crispy leaves?
Crispy leaves developing as it flowers. Seems to just be those that had some spots from what appeared to be a magnesium deficiency. I hit it with cal-mag and the spots stopped but recently the most affected leaves are shrivelled. Only maybe 4-6 leaves right now.
