My plant got this overnight it seems. White dots appear like if someone 'flicked' salt water at my plant. Also it's been doing this for a while. Leaves are drying up at the bottom. As they dry I have to pick them off. Here's a leaf from the bottom of the plant showing the condition. I started bringing in my plant during the night time because it started flowering. I sit the plant under a small florescent and uv light, about 75 watts. There are deffs no signs of spider mites, or webs for that matter. Did wattering the plant in the closet create a mildew? Is mildew air born? and what do I do about the yellow leaves drying up?
