Sarah's oncidium (store-bought summer) had black spots, repotted in bark, did well, now spots return with vengeance, leaf tips brown/gray. Waters 2×/week due to shriveled pseudobulbs. Afternoon sun window (African violet likes it). Feeds 3 weeks on, 1 week off. Expert: sunburned leaves—move from window. Leaf tip dieback = salt buildup. Pseudobulb shriveling = root rot (good repot). Flush with water several times, then feed ¼ tsp/gal 2×/month. Overall healthy with new growth. Reduce light, reduce feeding after rainwater flushes. No insect signs = other orchids safe for now.
