The EC of my water without fertilizers is 260 us/cm. Should I do a root flush and spend 2 weeks watering only with water before harvesting? The pH of my water is 9.5, should I adjust the pH of the water for the root flush as well? Thanks!
Hi there!
Yes 1-2 weeks of flushing the soil before the harvest is adviced for better quality smoke. Some people say flushing is a myth but I still like to believe in it.
Also the pH should be balanced to 6-6.5 so the plant can use the nutrients left in soil without any lockouts
