Triches are clouding. What is the orrect flush schedule now?

this grand daddy purple clone was planted on 5/12 using zen blend organic soil and fox farm nutrients… the cloudiness has begun and am waiting on 50% amber to harvest. when is the proper time to start flushing and how many times should that be done?

Flush 2 weeks before harvest

And you’ll want to do a real flush first, where you rinse your soil of all chemicals and nutrients.
Once you do that, you’ll only use plain pHed water until harvest.
