Leaves twisting

Looks healthy mate, well done. I would say it msg be a slight too much nitrogen in the soil or the light is too close but really I think you're fine.

I agree with martin, I've grow a few plants that were twisted and unusual leaf development the first few nodes and then it goes away. Otherwise twisting later in growth can be a response to heat, mites, wind, or a micronutrient deficiency.

Hello friend don't worry if is first set of leaves . It happens often with all these mixed genetics this days. And slight stress isn't always a bad thing. Keep growing and keep calm. Hopefully this helps.
