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.

Yellow crispy burn spot leaves
Does anyone know what could be causing the curling upwards on the leaves and burn spots, Yellowing as well? They're 7 weeks into flower and have been fed fox farms nutrients each other watering the whole grow until last week. The past week I have used plain water. Ph&PPM fine.

Why are some leaves curling strangely?
Hello everyone, the problems begin unfortunately. Why are some leaves curling strangely? I have not given any nourishment, the temperature and humidity are constant, will it be a problem of PH or EC? Thank you in advance.

What’s Happening Here With My Leaves?
Not sure what’s going on here. It’s happening to 3 of my plants and I’m not sure whether its good or bad. I haven’t watered in 3 days so I don’t think it’s overwatering because it just happened today.

Calcium Deficiency ?
Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?
Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas. Algunos tallos están morados.

Brown rust spots on oldest leaves
Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?

Outward Edge Curl
Noticing an inward curl to the outward edge of leaves. Happened before any nutrients. Temperatures for the tent have bit 78-94 with some times sticking in the low 90s for hours. Have been able to keep the tent in low 80s the last few days. Anyone else have a suggestion?

Hey guys. Leaves not curling upwards as such but I'm getting some leaf tips that seem to be reaching upwards slightly. Does this mean I need to up her cal and mag intake? I read somewhere if the leaf tips are starting to "pray" towards the light it could be a cal/mag def?

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.
