mcflowanswered grow question a year ago Switching from organic fertilizer (like Biobizz) to chemical ones (like Canna) mid-grow can be done, but it requires some considerations:
Gradual Transition:
Make the switch gradually to allow plants to adapt. Start by introducing the new fertilizer at a lower concentration and monitor plant response.
Nutrient Variability:
Organic fertilizers release nutrients slowly, while chemical ones provide them more immediately. Be mindful of potential nutrient level variations and adjust accordingly.
pH Adjustments:
Check and adjust the pH of your nutrient solution accordingly. Different fertilizers may impact the pH differently.
Observation:
Watch for any signs of stress or nutrient imbalances. Plants may respond differently to the change, so close observation is crucial.
Flush if Necessary:
If you encounter issues or notice nutrient imbalances, consider flushing the system to remove any remaining organic residues and start with the new fertilizer.
Monitor EC Levels:
Keep a close eye on Electrical Conductivity (EC) levels to avoid overfeeding or underfeeding. Adjust the nutrient concentration based on plant needs.
Evaluate Plant Health:
Regularly evaluate plant health, growth, and overall performance. If the plants respond well, you can continue with the new fertilizer.
Remember that switching fertilizers can impact the soil microbial community. If you've been relying on the soil food web in an organic system, the transition to chemical fertilizers may affect microbial diversity.
