Even with the best setup, occasional issues can arise when growing plants hydroponically. Don’t panic—most problems are easy to fix once you know what to look for. Here’s a guide to troubleshooting common hydroponic tower problems and how to solve them. π
Yellowing Leaves (Nutrient Deficiency)
π Problem: Yellowing leaves often indicate a lack of nutrients, especially nitrogen.
β
Solution: Check your nutrient levels and pH. If the pH is off (above 6.5 or below 5.5), the plants may not be absorbing nutrients properly. Adjust the pH and add nutrients as needed.
Root Rot (Too Much Water)
π Problem: Brown, slimy roots and a foul smell are signs of root rot, caused by excess moisture and poor oxygenation.
β
Solution: Ensure the pump is running properly and that roots are not completely submerged in water. Flush the system with clean water and consider adding a root treatment.
Algae Growth (Too Much Light Exposure)
π Problem: Green or brown algae growing on the tower or in the reservoir can deplete nutrients.
β
Solution: Keep the reservoir covered to block light and clean the system regularly.
Slow Plant Growth (Nutrient or Light Issues)
π Problem: If plants are growing slowly or looking weak, they may not be getting enough nutrients or light.
β
Solution: Double-check your nutrient solution mix and ensure plants are getting 12-16 hours of light per day.
π‘ Quick Fix Tip: When in doubt, do a quick flush of the system and restart with fresh water and nutrients.
