I am currently preparing the seedlings for next springs growing in my garden. I have created my own green house - in theory with ideal conditions (full spectrum lights, high humidity, 30+°C all the time). However I initially misread that more light is better for plants and for the first 3 weeks essentially gave them light 24/7. This did not go well and after a while the leaves started to crumple from the outer edge. Doing some research I realized that this could be from over exposure to light.
After going on a 12/12 schedule with light/darkness all the new leaves developed perfectly fine and no crumpling happened anymore, so this really was the reason for the crumpling.
Now to my question: Those crumpled leaves are still green and look fine on the seedlings after more than one week. They dont turn yellow or brown, they are just like a badly crumpled up piece of paper. I was wondering: Should I remove those leaves or keep them on the seedlings until they fall off on their own?
