I’m suspecting mold so i’m gonna be cutting a week early probably on the 30th of December. So to do a proper flushing i watered twice as much as i did ended up with 750 then 500 Ppm by the end of the week.
That's kind of weird for a smell . Did you try to smell the soil ? What's your water schedule like ? Do you wait till the pot is very light . Pm me if you would like .
