Leaves curling up

LST can't cause weird leaves, but genetics will. Your plant is just "a little strange" and may grow out of it and produce normal leaves soon enough, but if after the next two or so nodes continue with the mutated leaves, you will have to decide if you continue with her or give her the chop and put it down to experience. Hopefully she will start growing normally soon enough. Personally, with plants that I have had that did similar strange things, they stayed strange and ended up getting chopped. You can sort of tell by looking at it that it just isn't right and will end up being a waste of time and effort. Hope this helps,... Organoman.
