little taco, little curling...
both can have different causes.. Is environment within a safe range?
early leaf curling (before 7-9 lobed leaves / first few nodes etc) usually won't be seen later on, in my experience.
it can be from unequal growth spurts (twisting). this could be from ph swings etc. which could be caused by more than one behaviour too.
more info needed, but you can probably check on environment and find the cause in most contexts. temp and RH%.
>30C will be start of issues for some.. maybe =>33 to 35C for others. You don't want your RH -- 30%<=x<=65ish... (some exceptions for seedlings and clones... this is for a mature plant only... and if your VPD chart says otherwise too.) In general <65% is good for avoiding microbial growth.... but microbes can grow in lower RH too.. just won't be as fast of reproduction for most. slowing things down is important. it could be all a plant needs to fight something off, whereas an uptick in microbial production may be a tipping point.
