Well, to my surprise, I found that my timer had malfunctioned and the lights were on for 20 hours. the heat in my closet dried out the moisture at the bottom of the wooden box (the humidifier was dried out) and some of Julie's leaves crinkled up. I turned off the lights to give the mangoes their night and sprayed them down and by 6pm I turned back on the lights and let the humidifier do its magic. I'm gonna wean them off the humidifier soon.
