Mottled leaves on streptocarpus
Almost all of my streps have recently come down with the same problem: the leaves have a metallic brown-looking mottling on them, and the flowers are growing in on much shorter stems than before. I can't find a description of this problem anywhere...can someone help? I haven't done anything differently that I can think of. They are under fluorescent lights and also get a bit of late afternoon western sun. Could they be getting too much light? Thanks!
