S.O.S. Powdery Mildew 2 days before harvest

Day 56 and I see some beginning spots of PM.

Was putting off buying a dehumid for another room since temps are getting hot and It screwed me. Went and got proper dehumid needs today.

What do I do?

I just put them into darkness for 48hr.

Should I spray them with an h202 mix?

Should I wash them in a h202 mix when I chop and hang them?

Help save my crop please!!

Immediately budwash...like NOW.
PM will spread, and quickly.

Those are nowhere near ready BTW..weeks yet.
High ph'd water sprays...9 or 10 poor higher...PM does not like alkaline conditions.
Be wary of your buds.
Good luck.

That one bud your seeing that doesn't look ready is one of the only phenos in the room thats not ready or 7ish days from ready.

So spray with 9 or 10ph?

Have you heard of "washing" when you harvest - something like filling a 5gal with deulted 35%h202 and having another 5 gal of clean water and dipping your branches in them one after the other when you go to hang? Thoughts on this? Would it be damaging to terps?

Not too worried about harvesting too early as it is. Trying to get on a harvest every 4 weeks schedule. More concerned with stopping the spread of pm

I wash buds, cup of 3% peroxide to 2 gallons lukewarm, then a water bucket rinse before drying. Gentle swish doesn’t affect trichs at all. I would spray them now too.

Spray them with this same dilution ratio? 1 cup 3% h2o2 to 2 gal water

Never had pm, but i bud wash.

Jhef if you can get it in time Dr Zyme's Eliminator will dissolve all your PM and spores in a 15 minute post harvest wash, I find it works better than Hydrogen peroxide. Works as a foliar spray too.

Awesome will definitely grab that - Can you explain how to do a 15min wash? dilution ration do I set the branches in a bucket for 15min?

.

I wet trim so I just dumped 2 gallons of warm water into a 5 gallon bucket, add 4 ounces of Eliminator per gallon of water.

Dump the harvest into the bucket and push the buds under water with your hands.

After 15 minutes rinse in fresh water and hang to dry.

.

If You're doing a dry trim washing the buds still on the branch is a bit harder. Rather than a 5 gallon plastic bucket I'd recommend a rectangular plastic bin.
