Tiny-calyx Columnea problems — and how to fix them

Whitefly
Tiny white flying insects congregate under leaves and sap vigour. Yellow sticky traps will monitor numbers; treat with insecticidal soap spray applied to the underside of leaves in the evening to avoid sun scorch.
Crispy or browning leaf edges
A direct symptom of insufficient humidity. Increase ambient moisture via pebble trays, misting, or a humidifier — low humidity below 50% RH causes this species to deteriorate noticeably.
