Here is the update:
Because none of the issues seemed too dire, I decided to wait to flush the system. I did dilute the nutrients by toping off my reservoir, which had gotten very low because of a recent heat wave. But I wish I hadn’t waited to flush because I have now developed new problems. Here is how I took care of my second batch of issues:
- Diluted the nutrients.
- This problem did not multiply, but seems to have changed into holes, or this may be a separate problem.
- Was most likely a nitrogen overdose, or nutrient burn.
Curling and browning leaf tips:
- No more leaves on the new growth are brown on the tips or curling. I think that diluting the nutrients has solved the problem.
- In the future I am going to add no more than 75% of the nutrients instead of full strength to avoid this.
