I bought this flask a few weeks ago - Renanthera Citrina. It had a few white hairy growths on the roots, which a friend said were just hair roots . I know my place is a little warmer than where they were before and there seems to be more of them. The are not spreading quickly at all, and only on the roots, but I am concerned they are a fungus or mildew - not hair roots Can anyone tell me if I have something to worry about here...
