It’s actually a form of mold Defoliate the infected leaves And get more airflow And reduce humidity to just under 50 Hope this helps as I’ve had the same problem Happy growing

pH fluctuations will cause similar issues... check the pH of the water/feed going in and check again coming out. If everything is good, then it also has some similarities of Nitrogen def. Hope that helps. Happy Growing!👉😁👈
