Two-Spotted Spider Mite Infestation

Extreme Low Humidity (Environmental Stress)

While not a direct cause of webbing, extremely dry air can stress Chrysanthemum 'Pico Fluo', making it more susceptible to mite attacks and causing the plant's natural micro-hairs to trap dust in a web-like pattern. This is often accompanied by crispy leaf edges.

How to confirm: Check if the ambient humidity has dropped below 40% and if leaf margins are turning brown and brittle.
