Hey everyone, first time poster here. I'm having an issue with some of my hydroponic basil...the leaves and new growth are deformed and almost look like they are missing pieces out of them. Here's what I know:
- It is not a bug problem (I have inspected with microscopes
- Growing in 8" Rockwool Big Mama Blocks
- pH is 6.1
- EC is 1.2
- Irrigating 2x per day
The plant was looking great for the first several weeks...and now I can't seem to get it back to normal. Has anyone seen this? Any thoughts? It seems like it would be a nutrient issue to me.
Thanks for the insights!

If the leaves of your hydroponic basil plant are misshapen, there could be several potential causes for this issue
Nutrient Imbalance
Solution: Ensure that your hydroponic nutrient solution is properly mixed and within the recommended concentration for basil. Monitor the pH level regularly, as nutrient absorption can be affected by pH fluctuations. Adjust the nutrient solution as needed to provide the right balance of nutrients.
Lighting Issues: Inadequate or excessive light can also cause basil leaves to become misshapen. Insufficient light can result in elongated, stretched-out leaves, while excessive light can cause scorching or leaf curling.
Solution: Adjust the placement of your hydroponic basil plant to provide it with the right amount of light. Basil typically thrives in bright, indirect light, so ensure it receives around 6-8 hours of light per day. If using artificial lights, position them at the appropriate distance from the plant to avoid light stress.
Temperature Stress: Basil is sensitive to extreme temperatures. Cold temperatures can slow down growth and lead to misshapen leaves, while excessive heat can cause wilting and leaf curling.
Solution: Maintain a consistent temperature range suitable for basil growth, ideally between 65°F to 85°F (18°C to 30°C). Avoid placing your hydroponic setup near drafty windows or heaters that can cause temperature fluctuations.
Pest or Disease Infestation: Pest infestations or diseases can also cause abnormal leaf growth in basil plants.
Solution: Regularly inspect your hydroponic basil for signs of pests, such as aphids or spider mites, and take appropriate measures to control them. Additionally, ensure good ventilation and avoid overwatering to prevent fungal diseases.
Genetic Factors: Sometimes, certain basil varieties may naturally exhibit slightly different leaf shapes or sizes.
Solution: If the leaf shape is characteristic of the specific basil variety you are growing, there is no cause for concern. However, if you notice sudden and drastic changes in leaf shape, it is more likely due to environmental factors.
