Common Diseases
Nutrient Deficiency
Yellowing leaves, stunted growth, pale coloration, loss of reddish tones under high light
Increase fertilizer dosing (macro and micronutrients), ensure adequate CO2, and verify lighting is medium-high; perform 25% water changes weekly
Algae Overgrowth
Green or brown algae coating leaves, reduced photosynthesis, plant decline
Reduce lighting duration to 8-10 hours daily, increase water changes, add algae-eating shrimp or fish, and ensure CO2 levels support plant growth over algae
Melting (Leaf Decay)
Leaves becoming translucent, mushy stems, rapid tissue breakdown after planting
Ensure stable water parameters (pH 6.0-7.5, temp 23-28°C), provide adequate lighting and CO2, and trim affected portions; plant may recover within 2-3 weeks
Slow Growth
Minimal new leaf development, compact form becomes even more stunted, pale leaves
Increase light intensity to medium-high (8-10 hours daily), boost CO2 injection, and supplement with all-in-one fertilizer; growth should improve within 2-3 weeks
