Russets are a bitch.
You can flower them out, but you risk having them spreading everywhere.
I'd they were clones, thats how you got them...somebody gave them to you. Or you got them from a grow store. They are spreading up and down the east coast due to fuckers from Cali sending infected plants out here.
Depending on where you are (us or Canada) somethings will be unavailable to use or get.
Spray them daily with 2oz/gal flying skull nuke em...that will at least stop them, but you have to do it at least every other day until the end. Russets wipe out entire out door harvests in Washington, Oregon and Cali every year.
Long term solutions are limited, but they exist.
1) the true death nail to them is
forbid 4f. That shit is deadly and would read up on it if you think you want to go that way.
2) conserve sc...11.9%
spinosad a & d...The next best thing...super strong, will be picked up in a test up to 40 days. This should only be applied in veg. This is for MAJOR infestations.
3) flying skull nuke em @ 2oz/gal every other day and then
Venerate xc by Marrone every 5th day....this option is omri listed, but you have to keep on it.
4) rip it down, bleach everything, through away every pot, tool, tray...basically the entire setup, and start over
You can also fight them with predators...call Arbico organics in AZ they will hook you up with those.
