Should i throw them away? 4 weeks into flower can see it all over the plants in various places. I used regalia on these when they were young too.

40-60% RH entire grow
60-78F temps
Good air movement and fresh air exchange

Anything worth spraying them with this late or are they done for?

At 4 weeks, you should consider cutting your losses and starting over. You have a contaminated environment, and something is wrong. Are you sure your airflow is good and your humidity doesnt jump at night?

De humidify and try a copper based fungicide. You beer drinkers enjoy hops treated as such.

Been there and much worse. Hops grower convinced me to try. Use same ratio as for hops. It works.

I do suggest 105=110 F wash with H2O2 when trimming.

it looks like it just started to show? Just spray it. If it were me I would soak the shit out of everything with purecrop1 30ml/gal at lights out then just do preventative maintenance sprays at 15ml/gal every few days, for the preventative maintenance sprays you won't need to drench them like the first spray but you will want even coverage..

Wash them in 1 gallon of water and 1 cup of H2O2. It'll come off.

A formal 2 part bud wash would make the world of difference and not only wash off PM, but would disinfect them, get rid of dust, hairs, mites and bugs, and any other nasties that land on them.
