Common Diseases

Nutrient Deficiency (Iron/Micronutrients)

Symptoms

Yellowing or pale leaves, stunted growth, leaf necrosis starting at leaf tips, overall decline despite adequate lighting

Treatment

Increase liquid fertilizer dosing, particularly all-in-one formulas containing iron and trace elements. Perform 25% water changes weekly and ensure CO2 supplementation is adequate

Algae Overgrowth (Black Beard/Hair Algae)

Symptoms

Dark filamentous or brush-like algae coating leaf surfaces, reduced photosynthesis, plant decline

Treatment

Reduce lighting duration to 6-8 hours daily, increase water change frequency to 50% weekly, manually remove affected leaves, and boost CO2 and nutrient levels to outcompete algae

Root Rot (from Poor Water Quality)

Symptoms

Mushy or blackened stem base, foul odor from substrate, plant collapse despite adequate lighting

Treatment

Perform immediate 50% water change, improve water circulation, ensure substrate is not compacted, verify pH remains 5.5-6.5, and consider adding root tabs with beneficial bacteria

Melting (Transition Shock)

Symptoms

Rapid leaf dissolution, transparent or translucent foliage, overall plant deterioration within days of introduction

Treatment

Maintain stable, soft acidic water (pH 5.5-6.5, GH below 4), ensure high CO2 levels (30-40 ppm), increase fertilizer dosing, and be patient as plant may recover over 2-4 weeks
