How to make a good soup for hydroponics?

It seems like you're dealing with some challenges related to nutrient management and pH control in your hydroponic system. Maintaining the proper nutrient strength (EC/TDS) and pH levels is crucial for the health and productivity of your hydroponic plants. Here are some steps to help you address these issues: Starting EC: If the manufacturer's recommended nutrient dosage is too strong for your plants, it's a good practice to start with a lower EC (Electrical Conductivity) and gradually increase it. Since you've already reduced the dosage by half, keep an eye on your EC levels to ensure they are within the desired range for your specific growth stage (vegetative or flowering). pH Issues: Low pH can be problematic in hydroponic systems. It can lead to nutrient imbalances and nutrient lockout. To raise the pH without significantly affecting the EC, you can use pH Up or pH Plus solutions. However, as you mentioned, sometimes adjusting the pH can cause fluctuations in EC due to the nature of these chemicals. Be cautious when making pH adjustments and do so slowly, allowing time for the solution to stabilize. pH Buffering: It's essential to maintain a stable pH within the appropriate range for your hydroponic system. Use a good-quality pH meter and pH buffer solutions to calibrate your meter regularly. This will help ensure accurate pH readings and prevent erratic pH adjustments. Regular Monitoring: Keep a close eye on both your EC and pH levels. Check and record these parameters daily or as needed, especially during the nutrient solution changes. This will help you identify trends and potential issues early. Nutrient Solution Changes: If your EC becomes too high and difficult to manage, consider replacing some of the nutrient solution with fresh water. This will dilute the nutrient concentration and bring down the EC. Then, you can adjust the pH accordingly. Nutrient Mixing: When mixing your nutrient solution, make sure to follow the manufacturer's instructions accurately, considering your water quality and the specific requirements of your plant's growth stage. Water Quality: Assess your water source for its initial EC and pH values. Using reverse osmosis (RO) water or dechlorinated water can help in controlling the starting parameters and reduce the need for excessive pH adjustment. Consult with the Manufacturer: If you continue to experience difficulties with your specific nutrient product, consider reaching out to the manufacturer or their customer support for guidance. They may be able to provide recommendations based on their product's characteristics and your specific circumstances. Remember that maintaining the right nutrient levels and pH can be a learning process, and it may require some trial and error to find the right balance for your hydroponic system and plants. Keep detailed records of your adjustments and results to refine your nutrient management techniques over time.
