Brown spots on leaves of new African Violets
I ordered AV's from one of the retailers people mention on this site and have had them 3 weeks. Some are developing brown spots on the leaves which then turn soft. The spots seem to start out shiny then turn brown or they're copper/brown color. I have them under a grow light 12-14 hrs a day, fertilize with half solution of AV fertilizer, only water when the soil feels dry, and let the water run out the bottom of the pot. I need help from the pros on this site.
