Should I start flushing? Or do I not flush plants in coco coir? Or do I still have a while to go? This is a “Skywalker OG” auto.
Thanks

Nick they look fabulous and you're getting close. You have a little longer to go. But damn they are gettin' huge and they look good! You've done great.
Flushing is for cleaning an overfed substrate in hydro. You use it to keep any retained salts from burning your plant. Since I typically overfeed and don't necessarily run enough extra through the pot everytime I fertigate when my reservoir empties I run a low osmolar solution (seedling feed level) through my coco to clear retained salts then I mix the new reservoir and continue on feeding at age appropriate nutrient levels until it empties again, about 2 weeks. So flushing at the end is unnecessary and reduces yield.
But once a nutrient has passed into the root system the only way you can remove that is by supporting the plant's metabolic processes. You get smooth, clean smoke from your slow dry so the plant can break down the final nutrients, some of the chlorophyll et cetera. So now it's preparing for getting your dry on point.
Good job, you're almost finished!
