90% cloudy, check the transparence on the black backscreen. Its black color is barely shining through/ you can beraly see through them. Its perfect time to flush now, you can harvest in 10-14days? Or even later, all a thing of preference and what you want. I Would flush for atleast 10days, 14 better imo. But i saw a lot of people only do around 7 days, so think that should work too
