Use greencure half strength on flowering plants to combat pm. Prolly have to use it once a week until harvest. I had to rescue a growroom that was overrun with pm, both In the flower room and the mother room. Eagle-20 works, and it works permanently. I would spray my mothers with it, and spray plants that are going into flower the first day of flowering and your pm problem will be gone. It takes e-20 about 60 days to be out of the plant, so I wouldn't spray them after the first day of flowering. It worked for me, and almost a year later I am pm free!!
