The frequency with which you should change the water in your hydroponic system depends on several factors, including the type of system you are using, the plants you are growing, and the stage of growth. Here are some general guidelines:

1. Nutrient Solution Change Frequency:
   • Small, Simple Systems
   • Larger, More Complex Systems
2. Plant Growth Stage:
   • Seedlings/Young Plants: Change the water more frequently, about every two weeks, to ensure optimal nutrient levels.
   • Mature Plants: Every 5 weeks, but monitor the nutrient concentration and water quality.
3. System Monitoring:
   • Regularly check the pH and nutrient concentration (EC/TDS levels) of your water. If you notice significant changes, it's a sign that you may need to change the water sooner.
   • Top off the water level with fresh, pH-balanced water as it evaporates or is taken up by plants, but remember that topping off is not a substitute for a full water change.
4. Signs of Water Degradation:
   • If the water starts to look cloudy, has a foul odor, or if you notice algae growth, it’s time to change it immediately.
   • If plants show signs of nutrient deficiency or toxicity, it may indicate that the water and nutrient solution need refreshing.
5. Environmental Factors:
   • In warmer climates or during summer months, you might need to change the water more frequently due to increased evaporation and potential for nutrient imbalances.

By adhering to these guidelines and regularly monitoring your hydroponic system, you can ensure that your plants receive optimal care and nutrition, leading to healthier growth and better yields.
