wrote: I have seen something like it here a few years ago. It was caused by cyclamen mites, but as Snowhermit mention, calcium deficiency have similar symptoms, boron defiency too. In both cyclamen mite attacks and calcium def. the top leaves become brittle and later die back, but in the case of mites, the leaf will often be bronze colored beneath like on the photo. |
