Low humidity
Calatheas are more sensitive to dry indoor air than many common houseplants. Measure humidity rather than assuming.
Inconsistent watering
Repeated drought followed by heavy watering can damage leaf margins. Aim for steadier moisture without leaving roots waterlogged.
Water and fertilizer salts
Mineral buildup and excess fertilizer can contribute to crispy tips. Avoid overfeeding.
Harsh light
Strong direct sun can bleach or scorch delicate foliage. Bright indirect light is safer.
