Health of leaves Hello guys, I noticed that the new leaves seem a little curved down and puffed up. I don't know if it's because they just sprouted or can be a symptom of something. Can you give me an opinion? May 12 : https://ibb.co/6ZdSFKf May 11: https://ibb.co/dJ335

What is this leaf showing?Anybody knows what is going on with this plant? My first guess was nitrogen toxicity because of the leaves clawing down a week ago, but I am not fully sure anymore with how the leaves are looking now.

Damaged leaves The first two images are both the same strain with similar problems. The leaves are not developing to their full length, almost like they are cut in half. Also the smaller leaves are curling downwards and are completely stiff, almost crispy. Any idea what that might be?

Leaves hanging down Northern Lights, Autoflower, 6th Grow Week. Some leaves hang down weakly since a few days, especially the upper ones. The weird thing is, that some leaves feel a bit dry, other ones feel normal. The other plant, Critical Auto, looks absolutely fine and healthy.
