What concerns me the most is the fact the new growth leaves are shriveling inwards. the leaves especially the new growth leaves, have small white dots everywhere and the plant refuses to grow. Im sure I'm not over watering it since my soil drains quickly and when I dig a few inches soil is moist but not wet. I'm sure it isn't space since the pots are large enough to support fruit once they reach adulthood. The soil allows decent circulation and it's a cactus mix composed of humus perlite and sand .It has been fetilized normally like the rest of my plants so it isn't a nutrition problem. The rest of my papaya plants are thriving while this one is just sad looking in the corner refusing to grow and sick. I doubt sunlight is a problem since the rest of the plants grow great in the same area with lush large green leaves. Please help me I don't wanna lose this one.
