Green Cure and Stylet can be used up until harvest,
Green Cure will need to be very very light not to burn the plants but will wash away all PM. Stylet will do the same but is more of a wax base so it doesn't do anything to the plant really. Both are OMRI cert.
Eagle 20 is what has been recommended to me as the be all end all for PM from homies, but haven't got around to it yet. I will using next round for sure, if things pop back up.
I would also start using DM Zone as a systemic to the root zone. I started using last week, and now the only plants in the room that keep poppin up a few spots here and there are ones on flush with no Zone in the feed. Ones with Zone are holding strong in combo with Stylet. I will be trying the Eagle20 real soon, especially since I found out my yard was the cause of PM, not my room! LMAO.
