One seedling as u can see on the last photos, has ...

don't worry, they often look a bit strange in the beginning, i had some twisted leaves in my last grow too, that happens quite often, everythings looks fine to me! :) BUT: if u see twisted new grow in a later stage, it CAN be a sign of broad mites, but u will see other signs like yellowing leaves etc too. (u can only see broad mites with a microscope, if u have this, use neem oil and spray it on the whole plant (but never do this in flowering stage, u dont want neem oil in your buds!)). happy growing 😊
