I agree, she might be too wet, although I have seen plants at that size with twisted leaves before, I don't think it is anything to worry about. Not all plants are 100% perfect, 100% of the time. Expecting every plant you grow to be 100% perfect is expecting too much. Try, once you transplant her, to keep the soil moist, but not wet.
Also, plants at that age do not really need feeding if growing in soil. The plants are in rather small pots, so transplanting should happen soon. Another thing I noticed is that you are feeding her "bloom" nutrients, however she needs "grow" nutrients which has a different formula designed for optimum growth in cannabis plants. Feeding her "bloom" nutrients at this size/age means she is not really getting what she requires for best growth. Wait until after you have transplanted her before starting on feeding her and not until she has at least 8 or so nodes. Hope this helps.....
