Common Diseases
Nutrient Deficiency
Yellowing leaves, stunted growth, pale coloration, loss of red pigmentation despite adequate lighting
Increase fertilizer dosing frequency, ensure CO2 supplementation, test water parameters, and consider adding root tabs for macronutrient support
Algae Overgrowth
Green or brown algae coating leaves, reduced light penetration, slowed plant growth
Reduce lighting duration to 8-10 hours daily, increase water change frequency, add algae-eating shrimp or fish, and improve water circulation
Melting (Leaf Decay)
Leaves becoming translucent, mushy stems, rapid tissue breakdown after planting
Ensure stable water parameters (pH 6.0-7.5, temperature 23-28°C), gradually acclimate plants, improve water circulation, and remove affected portions
Slow Growth
Minimal new leaf development, weak stems, pale color despite adequate light
Increase CO2 injection to 20-30 ppm, boost fertilizer dosing, verify lighting is 8-10 hours daily at medium-high intensity, and check for nutrient deficiencies
