Common Diseases

Nutrient Deficiency

Symptoms

Yellowing leaves, stunted growth, pale coloration, leaf holes or transparent patches

Treatment

Increase fertilizer dosing frequency to weekly; ensure macronutrients (NPK) and micronutrients (iron, boron) are present in fertilizer formulation

Algae Overgrowth on Leaves

Symptoms

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

Treatment

Reduce light duration to 8-10 hours daily; increase water changes; add algae-eating fish or shrimp; manually remove affected leaves if severe

Root Rot (Substrate-Related)

Symptoms

Mushy stems at substrate level, foul odor from substrate, leaf yellowing and wilting despite adequate light

Treatment

Improve substrate drainage; increase water circulation with aeration; perform partial water changes; remove severely affected stems and replant healthy cuttings

Melting

Symptoms

Rapid leaf dissolution, transparent or slimy stems, plant collapse within days of introduction

Treatment

Gradually acclimate plant to tank conditions over 1-2 weeks; ensure stable water parameters (pH 6.0-7.5); maintain consistent temperature; increase water circulation and reduce bioload
