It is hard to say without knowing the plant, having pictures, and a detailed description of the care.
What I can do is give you some common reasons why leaves curl, and won't flower.
If the pH is too high, or too low it can cause leaf curl. You will have to test the pH of the soil before knowing how to correct.
Too much or too little moisture can cause this, depending on the plant.
Too much light can cause it, depending on the plant.
Too much of one nutrient, or not enough of one nutrient can cause leaf curling.
Lack of humidity or too wet, or too dry soil can cause this as well.
Lack of flowering can be caused by pH imbalance, nutrient deficiencies, or environmental problems, as well.
