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

Started LST but now plants look a bit sick?
I attempted to do LST but I think I've maybe started too early as some of the leafs started to wilt kinda bad afterwards. Was careful not to break anything. Edges are curling and have discolored. I have a feeling they're a bit short too? Photo from 5 days ago and today.

Is this nute or sun burn? What should I do to save my babies ?
I upped the nutrients to week 2 of veg state (biobizz) and put the light to 50% intensity. I put the light at 6 inches above recommended height (which is recommended on the Mars Hydro website for beginners). . IS THIS NUTE BURN OR LIGHT BURN?

New leaves have yellow and/or curled tips (-> nutrient burn?), and many leaves have their edges curled up (-> root problem?). The pot that I'm using is fairly small and only has a small hole for drainage. Can this develop into a serious problem?

Tips of leaves turning (again..)
Why are the tips of leaves curling up again? This is happening only in one plant. Other plants are looking very healthy, this too but the leaves are just playing around. pH and EC are right and it shouldn't be too hot.

Magnesium Deficiency ? How can I fix it ?
got a little deficiency (maybe burned? but I think not). I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

Yellow and fragile leaves 2 week
Couple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn. For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

Does anyone know what this is? Just before this happened the leafs were cupping upward. She’s in coco coir and perlite. I feed her biobizz grow 3ml/l and biobizz heaven 4ml/l and cal mag 1ml/l and ph the water to 6.3 about 6-7 weeks into veg and this is the first problem I’ve had

Super Urgent, first time grower, batch might go to heaven - plants look beaten up, I suspect light stress or overwatering
5 plants, 4’x4’x6.5′ grow tent, 600 watt HPS lamp (it is hanging 70 cm above the highest canopy plant), did topping on 2 of them, swithing to fowering very soon, average humidity is 30%-50% (can't afford a humidifier now, so I use natural methods) for now), 2 static fans

Curling and twisting leaves (main bud polyploid?)
Hi cannafam, the leaves of this Blue Amnesia Auto are turning, twisting and curling up a bit.. Anyone know if overwatering might be the problem? Have been watering (and feeding) her as much and as regularly as the others (no prob there), but she is a bit smaller and skinnier

Leave curl weird shape
Yeah this plant curled the first 3 set of leaf but others plants in the same condition don't do that. I wondered if it somekind of genetic issue or it's just normal ?

Hello, So my WW look almost ready for harvest but she is still Young (end week 8). The temperatuur start to cool down here. Do I best wait to harvest her (around week 12) or do I follow my instinct and end her in a week or two? Thanks grow friends!

Leaf curling cause - Humidity, nutrient or overwatering
Hey fellow growmies, Leaves are curling and fading which I have seen in other grows for this strain. Do you know what might be causing this and how best to remediate? Humidity has been high recently ie above 60% for large periods Watering has been consistent Nutrients reduced TY
