ok, so where to start. First thing that is needed to even begin answering this question is more info. Room temps, room humidity, light type size and distance from cutting, type of media used, ph and ppm and ingredients added to ur watering in solution, are they in a humidity dome or are u misting them (if so how often), what type of rooting hormone was used and how much? Some pics maybe helpful. Also how many days ago they were stuck?
