Orchid Black Spots & Yellowing: Root Rot Primary, Check for Mealybugs

orchid

Black spots, yellowing. Fungal? Mist daily. Photos attached.

Primary Suspect: Root Rot

Unpot and check roots. At least one major issue = root rot from overwet mix. Confirm by root exam. Possible mealybugs at base (white fuzz) or white mold—photo not magnified enough. If rot present, weakened plant invites fungal infection.

Action Plan

Check roots; remove dead.
Remove dead/damaged leaves.
Soak in antifungal solution before repotting.
Grow drier going forward.
