Hello everyone, I am curious if there is any fungicide that can be used up until about a week before harvest give or take? We have had a bunch of rain and cooler temperatures and want to apply something as a preventative. My plants are at different stages of flower with some about 2 or three weeks from harvest. Thanks all.
Is any fungicide safe in flower?

potassium bicarbonate
But it will cause your pistils to prematurely brown if you run it too hot.

My plants have white mildew so i spray them down with milk, mix 1 part skim milk with 9 parts tap water and soak the plants. I spray first thing in the morning so the sun dries it quickly. I use a 2 liter pump type sprayer, soaking so it washes the leaves and buds. Plants are coming along great, cannot see any negative effects, plants even smell potant and fragrant.

Moderate growth inhibitor at best with milk. H2O2 and cider vinegar will oxidize your leaves and hairs. I'm dealing with the worst PM in experience ever. And everything in my yard. Tried all the home remedies. Just applied Regalia as suggested by a verified expert. Don't mess around on maybes. Preventatives from the start. And something that will work organically. Hence Regalia. Wish I had just went with it from the start. The extra money would have been worth the stress and labor of the failed remedies I've pursued. And I thought I had it figured out after my many minor encounters.
Will this work all through flower? Is this organic? Thanks

Or so I have been told. I'm mid bloom. Still should have started with it. No PM in the first place. I've lost 50#'s of foliage so far. And 18 hours removing it.
Where do you purchase this at?

h202, very economical and safe for plants in flower when diluted as directed

A dunk in h202 at harvest is also my preference. The 35% concentration bottle will make hundreds of gallons

I first noticed the PM about 2 months ago when the plants were small, I was just going to toss them since I already had an indoor grow finish and have plenty. I decided to try the milk spray, 2 months later the plants look great. I think the key is using a good sprayer and getting every single part of the plant.

Ive had success everytime on small potted plants. Planted full size and overcrowded is a different animal all together.

It's all good. Lost about 25% of my yield. But I will still get a better run than most. Never put a greenhouse up mid run. LOL. These were beautiful.

Personally, if a plant have shown any signs of bug problems or PM during the grow I will actually dunk the fresh harvest before hang drying in an h202 "bath" . If your smoking outdoor grown, I'm sure your ok with some "organics" , even in a greenhouse, theres tons of mother nature probing the plants at all hours
