Can anyone tell me what I've done to this croton. I thought it was too little Water but watering it made it worse. I've told my daughter to stop misting it with the Shefflara. The room is fairly bright but the plants do not get any direct light. One of the lights on top is a gro light ( incandescent) temp at plant level is 75-80 degrees. Soil is an organic potting mix with stone in top of soul. Clay pot.
