why the top of cannabis leaf are clawing like the plant is looking super healthy is a big plant it has got a nic exolor on the leaf noot too green so there’s jot nitrogen toxicity , is just the 2-3 inches of the plat at the top which is doing that the rest of the plant the leafs are pointing up so u understand that is nothing to so whith too much nitrogen heat is a bit higher than it should but i have 9 plants in there the only one who’s doing that is this
Clawing is really only associated with excess nitrogen. You might have something like heat stress at the top, but that would be drooping. When leaves droop they look tiered. When leaves claw they curl down and back towards the stem. Couldn’t say one way or the other without a picture though. Just because the color looks good to your eye doesn’t necessarily mean it’s not a toxcicity.
