I have several new Ahi Dulce plants from seed, about 4 months old. They recently developed a brown leaf spot that decays within days. Have tried clipping, but it is persistent. Newer leaves are still intact for the most part. My soil is stock Miracle Grow Potting Soil. Only a few other varieties have had some of this, but much less severe, and those plants are much more along. I have tried Daconil for fungus, and a standard Ortho garden spray. Do not see any visible mites or other pests. Any advice?
