Incrementar el EC de água inicial sin la adición de abonos/nutrientes?

Increasing the EC is far more straightforward. In both hydroponics and soil, this is simply a matter of adding either more nutrient solution or your chosen fertilizer or additive. Make sure that you take EC measurements after dosing so that you don't end up overshooting your target

If you have water with very low nutrient content and your initial Electrical Conductivity (EC) values are below 0.4, you might need to raise the EC to provide your plants with the necessary nutrients. Here are a few ways to increase the nutrient concentration in your irrigation or hydroponic solution: Nutrient Supplements: Add appropriate nutrient supplements to your solution. This could include commercial hydroponic nutrient solutions that come in concentrated forms. Follow the recommended dosage on the product label to achieve the desired EC level. Individual Nutrient Elements: If you prefer a more customized approach, you can add individual nutrient elements to your water. This might include sources of nitrogen (N), phosphorus (P), potassium (K), and micronutrients. Make sure to calculate the amounts accurately to achieve the desired EC. pH Adjustment: Check and adjust the pH of your nutrient solution. Nutrient uptake is influenced by pH levels, and maintaining an optimal pH ensures that plants can effectively absorb the added nutrients. Most plants prefer a pH range between 5.5 and 6.5. Monitor EC Regularly: Regularly monitor the EC of your nutrient solution using a reliable EC meter. This will help you ensure that the nutrient concentration remains within the desired range. Adjust the nutrient levels as needed based on the growth stage of your plants. Gradual Adjustments: Make changes gradually to avoid shocking your plants. Sudden adjustments in nutrient concentration can stress the plants. Gradual changes allow them to acclimate to the new conditions. Water Quality: Consider the overall quality of your water. If your water source has certain minerals or elements, they contribute to the overall nutrient content. Understanding the baseline of your water can help you make more informed adjustments. Calcium and Magnesium Supplements: Calcium and magnesium are essential nutrients. If your water lacks these elements, you may need to supplement with calcium nitrate and magnesium sulfate to achieve a balanced nutrient profile. Remember that the nutrient needs of plants can vary based on their growth stage. Adjust your nutrient solution accordingly, and closely monitor your plants for any signs of nutrient deficiencies or excesses. If you're unsure about the specific nutrient requirements for your crop or the best way to adjust nutrient levels, consulting with experienced growers or seeking advice from a hydroponics expert can be beneficial.

If you’re water source is below .4 EC - consider yourself lucky. If you’re using Reverse Osmosis water- you need to add CalMag and maybe some micros.. tho most nutrient lines will have that covered

add fertilizer? I don't fully understand your question.
