You may have given to much nitrogen for to long into flower causing dark leaves, the curling ones are from heat stress and the bending over ones are from the light.

Nute Burn? Or something else?
I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated

Tips curling up
I noticed the tips beginning to curl up. I did gave her bio grow in the last two weeks 0.5ml/lt ph 6.5 almost every watering i used bio grow. I have another 8 plants of different breeds and none of them showing anything wrong. I wander if its the nutrients or perhaps the light?

Leaves Curling inwards early veg
Hello I’ve noticed that the leaves are starting to curl inwards. It has been very hot over the last couple of days with temps in the high 20s and RH any where between 45-60. So not sure if this is heat stress or something else. Should this just rectify itself. Thanks

Leaves yellowing and curling
Leaves seem to be yellowing and curling upwards. Is this under watering or a deeper issue such as nitrogen deficiency?

Leaves curling is it due to light stress or wind over canopy? Have provided pictures of leaves labelled "leaves curling" and also lamp to plant distance. Lamp to plant distance is 1.5 to 2ft.All leaves affected are the ones closest to light .Any advice greatly appreciated.

Over watering?
Dude, what's the problem with this girl? The transplant was done 1 week ago because the pot was small. But since then the leaves have always seemed curled and dry. Could it be above water? The top and edges of the pot are dry but around the root ball is moist.

Leaf Curling - Late Flower
Growers, Small issue. LOADS OF LEAF CURLING. I assumed it was nitrogen so I stopped all nitrogen for 3 weeks & no fix. Flushed with 20L of water thinking its possibly salt? Nope still got a curling problem. Any ideas why this is happening & is it a big issue with 3 weeks left?

Why are the sides curling up? Question not about them pointing down but only about the sides curling up and very small brown points
What is this? Sides r curling up. Day temp didn't get over 23 degrees night temp is +- 12 so I don't think she got too hot. Points bit yellow Saw this yesterday evening too, today at 1 plant a little bit. They're probably pointing down because of the low night temp so that's ok

Brown area on leaves
Bonjours à tous. Voilà certaines feuilles de ma plante deviennent attrape des tâches brunes. J'ai donné du GHE essential (oligo-éléments) and cal magnifique (0,3ml/L) ce matin ainsi que du biographie Bloom. Je pense à une carence en magnésium et vous qu'en pensez-vous?

Leaves curling into bud
As sugar leaves send their nutes to the buds and start to curl/die, do I need to trim them off before the curled part reaches the buds? The fan leaves were an easy choice to trim...sugar leaves I’d have to trim the leaf rather than stem. Is that ok or necessary?

Have these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol. Several leaves have this. Combined with a slightly general canoeing, could it be from a nitrogen tox ? Growing good though Cheers
