Leaf curling up

My current White Widow grow had some weirdly bent leaves at first. The first 2 fan leaves looked disturbingly like half a swastika, but it grew out of it, and it seems to be thriving now.

By curl up i would say either heat or too much food. Fresh grow is nice, would not stress about it. Plant was touching grow medium, so that could influence too, main thing - fresh grow healthy....

I dont think you should be worried about it all. That looks like the cotyledon (seed) leaf. The plant looks really healthy and responded well to topping. Could be several things. just from being close to the soil. being the seed leaf like I mentioned, they tend to die off naturally. Although in healthy plants not uncommon to see them well into veg. looks kind of like wind burn too, but the other leafs are okay so probably isn't it.

Hi! I've seen leaf curling like that as a reaction to being topped. I think she will be just fine!
