How to fix a burn of nutrients?

If your plants grow in soil or on coconut, and you water them by hand, use clear water (without nutrients) with a balanced pH. This will "reset" your growing medium and allow the roots to recover from the problem they were facing. Don't worry, the roots will tap into the nutrients that are in the soil. Give them time to rebuild before adding more nutrients. Be aware, however, that damaged leaves never recover. Focus on new shoots to see the changes for a good recovery.

For soil culture systems, the pH should vary between 6.2 and 7.0. For hydroponic systems this should vary between 5.5 and 6.5.

If you are growing your plants in a hydroponic system, you will also need to add pH balanced water. This will dilute the amount of nutrients that are already present. In the next "diet" should also include less nutrients. Proceed with caution, however, as hydroponic systems always require a more gradual change. You may want to consider purchasing a TDS meter to help regulate / measure the nutrients that are in the water.
