Common Diseases

Nutrient Deficiency

Symptoms

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

Treatment

Increase fertilizer dosing with all-in-one liquid fertilizers or macronutrient supplements; test water parameters and adjust iron and trace element levels

Algae Overgrowth

Symptoms

Green or brown algae coating leaves, reduced light penetration, slowed plant growth

Treatment

Reduce lighting duration to 8-10 hours daily, increase water changes, add algae-eating fish or shrimp, and manually remove affected leaves

Root Rot

Symptoms

Mushy roots, foul odor from substrate, leaf yellowing and wilting despite adequate nutrients

Treatment

Improve substrate drainage, reduce organic debris buildup, increase water circulation, and consider replanting in fresh substrate if severely affected

Melting

Symptoms

Rapid leaf deterioration and transparency, particularly after major water changes or environmental stress

Treatment

Maintain stable water parameters, avoid sudden temperature or pH swings, ensure consistent fertilization, and remove severely damaged leaves to encourage new growth
