Common Diseases

Nutrient Deficiency (Iron/Macronutrient)

Symptoms

Yellowing or pale leaves, stunted growth, loss of vibrant coloration, particularly in new growth

Treatment

Increase fertilizer dosing frequency to 3-4 times weekly; verify CO2 levels are adequate (30-40 ppm); perform 25% water changes weekly to reset nutrient balance

Algae Overgrowth (Green Spot/Black Beard)

Symptoms

Green or black algae coating on leaves and stems, reduced photosynthesis, plant decline

Treatment

Reduce light duration to 8-10 hours daily; increase water column fertilizer and CO2 to boost plant growth; manually remove affected leaves; add algae-eating shrimp or fish

Melting (Tissue Decay)

Symptoms

Leaves becoming translucent, mushy stems, rapid deterioration of plant structure

Treatment

Increase CO2 injection to 30-40 ppm; ensure temperature remains 22-28°C; boost all-in-one fertilizer dosing; perform 30% water change; trim affected portions and replant healthy stems

Poor Growth/Stunting

Symptoms

Minimal new leaf development, weak stems, leaves remaining small and pale

Treatment

Verify high lighting (8-10 hours daily at 2+ watts per gallon); increase CO2 to optimal levels; dose fertilizers consistently 3x weekly; check that pH is 6.0-7.5 and hardness is 2-15 dGH
