Upward curl
GrischaBXL
started grow question 5y ago
Hi Breeders, Elizabeth is growing well, but the bigger leaves are curling up at the edges. I already increased lamp hight and lowered to 18/6. Is it air humidity? Or too much water?

When leaves curl (taco) it's usually a sign of heat/light stress.

Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

Curling leaves - heat stress?
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.

Any idea why the leaves are curling inwards like they are in the last two photos? Is this because it's too hot, or am I giving it too much water? Should my fan be blowing on the plant itself, or the 150-watt light? Thanks.

Dry brittle leaves
Discoloured older leaves curling up at the edges and turning dry and brittle. I think my problem is over or under watering. I've been very careful to avoid overwatering so I'm leaning towards the latter but what I've read online suggests dry/brittle means overwatering. Thoughts?

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

Fan leaves curling up
Some of the fan leaves are curling up at the tips. Not all of the leaves just a few and only at the longest petal. Is this something I should be concerned about?
