I have several african violets in a northern window that has a sheer curtain to filter the light. I've been noticing the past few weeks that the largest one, although still flowering, has yellow edges on it's outer leaves. are they being "burned" should I move it a lil further away from the window? I do only water when they are dry on top, never for more than a day or two. And fertilze with African fert drops once a month. The watering averages to be about once a week for the clay pots and 8-10 days for the plastic pots. I've had them for well over a year now, so I'm not sure what is going on. Any pointers would be great. Thanks!
