Repot in completely dry, fresh potting mix. Do not water for 3-5 days.
Stress reduction
Place in bright indirect light, away from direct sun. Reduce watering frequency significantly.
Organic Treatment

Prune affected roots
Using sterile scissors, cut away all soft, mushy, brown, or black roots. Cut back to healthy white tissue.
Apply cinnamon
Dust all cut surfaces generously with cinnamon powder to prevent fungal regrowth.
Prepare chamomile soak

Air dry roots
Let the roots air dry for 2-4 hours in a shaded area with good air circulation.
Prepare new container
Clean the pot with diluted vinegar, rinse well, and fill with fresh sterile potting mix.
Repot carefully
Plant in the new soil, ensuring the root crown is at the proper level.
