Karen's Sophrocattleya (8 pseudobulbs) has new leaves turn black and die; never bloomed. Treated like Phalaenopsis (weekly weak 15-5-5). Expert: grow drier. Water mornings only. Repot in fresh mix for better air flow. Fan to dry after watering. If no improvement, weekly morning copper fungicide on base. No humidifier—worsens issue.
