Succulent Leaf Yellowing and Drop: Light and Water Diagnosis

Unidentified succulent (possibly Sedum) shows yellowing, drying, dropping leaves, some green leaves with brown edges. Expert Will Creed: photo quality poor, but symptoms generic—caused by too little light, too much water, or too little water. Most likely: insufficient light and overly damp soil. Fix: sunny windowsill, let soil dry deep before small watering. Gradual improvement expected.
