Severe Dehydration/Underwatering Stress

Diagnostic note

This appears to be a tropical foliage plant (possibly Alocasia or similar) showing classic severe water stress. The uniform distribution of symptoms across the entire plant, combined with the dry papery texture of brown margins and generalized wilting, strongly suggests dehydration rather than pathogenic infection. However, root rot cannot be fully ruled out without examining the root system - chronic overwatering followed by neglect can produce similar above-ground symptoms. The lack of fungal structures, spots with defined margins, or pest evidence supports abiotic stress diagnosis.
