My plant leaf tips are curling down and there are small rust colored dead spots beginning to appear in the middle of the leaves. Whats going on?
The symptoms you describe are consistant with salt toxicity. Your plants are not able to take water up through their roots because there is too much salt in the solution. There are also probably too much salts lingering in plants roots etc. The solution to this problem is to drain the reservoir immediately and fill it up with fresh water. You will use this fresh water to leach the salt from the plants over a period of days. You can use a flushing agent such as Final Flush or Clearex to speed up the process. Keep an eye on the TDS readings of your reservoir. If they go very high, you may want to drain the reservoir again and keep flushing. After a few days you should notice signs of more normal growth and can switch back to your regular nutrient schedule.
