When to start water flush before harvest?

If you’re a week and half away from harvest that’s a good tome to start flushing. Depends on the medium being used. Soil if you let the nutrients deplete then you don’t really need to fhush as it has consumed all the food. Hydroponic set ups require less time for a flush because obviously it’s easy to chase all the nutrients out of the water. I’m in a soilless mix of peat moss and coco and perlite. I started week seven of flower. It may have been a bit early but I’m ok with leeching it early and letting the plant consume her fan leaves. That’s how you know the flush is working. If I were you I would start the flush. I personal would rather start it a bit early to make sure she’s flushed rather than being late on it and having buds that taste like chemicals and pop like the 4th of July. Happy harvest friend.
