Leaf cupping

Weed leaf cupping is a common issue that growers face, and it's usually a sign that something's off with the plant's environment. The leaves start to curl upwards, kind of like a taco, and it can affect the plant's health and yield if it's not addressed. There are a few main reasons why this happens. One of the biggest culprits is environmental stress. Things like heat, drought, or even too much light can cause the leaves to curl up as a way to conserve moisture. Nutrient problems can also play a role. If the plant's not getting the right balance of nutrients, or if the pH of the soil is off, it can lead to cupping. And sometimes, it's just genetics – some strains are more prone to cupping than others. Figuring out the exact cause can be tricky, since the symptoms can be similar. But if you see your leaves cupping, it's a good idea to check your grow environment, nutrient levels, and pH to narrow it down. Catching it early and making adjustments can help your plants bounce back and stay healthy. Alright, here's the deal with cupping leaves. It's usually a sign of stress, and there are a few main culprits. First up, heat and drought can really mess with a plant's water balance, causing the leaves to curl up to conserve moisture. Then there's herbicide drift – those chemicals can seriously warp leaf shape. And finally, pests like aphids or mites can also cause cupping as they feed on the plant. Nutrient imbalances, especially too much nitrogen, can also lead to cupping. The plant grows too fast and the leaves can't keep up. Overwatering or underwatering can stress the plant too, messing with its ability to take up nutrients properly. And sometimes, it's just genetics – some strains are more prone to cupping than others.

Hey there things like humidity and wind stress can be causing this but also your soil looks very wet sometimes when you over water you get some root damage and then the light intensity starts to affect the leaves cause the roots are not giving them what they need

Yep, cupping can be heat-related, but also check: Low humidity (under 50% in veg can cause it) Strong direct airflow (fans blasting the leaves nonstop) Light too close (intensity stress) Try to keep temps around 22–26°C and RH 60–70%. Doesn’t look serious yet — just keep an eye on it before it worsens. Plant looks solid otherwise!

Yes, it looks like mild heat or VPD stress. Nothing serious yet – maybe raise your lights slightly or improve airflow to cool them down a bit. She should grow out of it easily if conditions stabilize!
