Yellowing leaves, stunted growth, pale coloration, particularly in older leaves

Treatment

Increase fertilizer dosing with comprehensive plant supplements; add root tabs if substrate is depleted; ensure adequate lighting to support photosynthesis

Algae Overgrowth on Leaves

Symptoms

Green or brown algae coating leaf surfaces, reduced light penetration, plant vigor decline

Treatment

Increase water changes, reduce lighting duration, add algae-eating fish or shrimp, manually remove affected leaves if severe

Stem Rot

Symptoms

Soft, mushy stems that darken and decay, foul odor, leaf loss starting from base

Treatment

Remove affected stems immediately, improve water circulation, reduce organic waste buildup, ensure adequate water changes and avoid stagnant conditions

Melting

Rapid leaf deterioration and transparency, plant appears to dissolve, especially after major water parameter changes

Treatment

Maintain stable water parameters, acclimate plant gradually to new conditions, ensure consistent temperature and pH, trim damaged portions and allow regrowth
