I have a question about my Abelmoschus Manihot. I've usually wintersown them but this year I decided to try growing them under lights. I'm wondering if I may have them to hot. The plants are very healthy. The first time I noticed the problem was when I saw small white things on the stems and undersides of leaves, my first thought was white flies. I got out my luminex to check and these things were like tiny raindrops. The droplets are hard, not soft. Is that from transpiration? Could it be something else? I've attached a picture. Marric
