I need advice about the cold, stress, and the potential for PM in late flower.

I moved them under a deep awning a few days ago so they wouldn't get drenched Friday night. I'm in Eugene, Oregon and the autumn chill has hit. Night time low temps have been 45-50; daytime high temps have been 60-65... They are starting to tint purple from the cold, and they have noticeably slowed down already. There is no sign in the forecast of it hitting 70 again, and highs for the next day or two are looking closer to 60. In addition, the humidity has been 80+% due to continued intermittent light rain and heavy clouds. I spotted a teeny tiny circular patch of what could have been PM on a small lower leaf. I obviously plucked it immediately. I wasn't going to wait to find out for sure. This is my second outdoor grow, but I've never had so many large plants. Moving them indoors this time isn't an option, and the garage isn't really much warmer. I'm curious what you all would do in this situation? How far do you think they are from finishing in weather like this? Is this a cut your losses kind of situation? Still no amber; they seem mostly cloudy through the mini-microscope...

Here's some pics from various areas of the plants.

Best thing you can do is keep the moisture off those girls as much as you can .....and if you want insulate the root zone .....you can use straw or there's other ways also ......keep the roots happy and the moisture off .....there pretty hardy plants when healthy ....GL

Right now your enemy is mold and bud rot.. If you see a bud leaf that is crinkly on the end or just doesn't look right...
Give it a tug.. if it comes out easily... check that area and remove before it rots.. bad shit!

Thanks guys. I've been meticulously combing for rot and mold ever since the rain came.

Am I correct in thinking they are still about a week or two from harvest? And will this cold drag that out longer?

No the cold will force the issue and shorten the time.. with the weather we've been having I'd go a week and harvest..
Can't push your luck in the P Nw it's too humid..

That is exactly what I needed to know. Thank you for the advice.

I feel yer pain -- from WA. Already amputated at least a dozen branches this year.
It's hard to keep them dry, even if you protect them from rain.
I've found that trimming is the key to preventing fungus issues late in flower. Keep them open in the middle and make sure leaves do not overlap. If they do, whack em & you'll be glad you did.
Another trick is to keep wind on them. A strong fan will deter mold *and* pests, but it's not always feasible. Any breeze is better than nothing.
Still air at night is a fungus delight...

Powdery mildew is not the only fungus on the block. If you get this brown shit on a stem, the entire branch is toast.

I highly recommend you move your plants indoors if possible.
This Purple OG bounced back nicely after I brought it inside. Might be a keeper if it finishes well.

I got some of that on one my branches uses hand sanitizer to clean it all off no more problems been a couple weeks it's still looking good

Well, after verification that I have about a week remaining, I jumped up and started rigging this little number. I'd love to bring them in, but it just isn't feasible at this time.
I did quite a bit of thinning some weeks ago, but I'm wondering if it was enough. I have a fan running warmer air under the canopy from the house and the soil there is very very dry still. It's on the east side of the house so it doesn't get nearly as much direct light but it also stays much drier for longer.

The buds on that branch won't be as good as the others. You can keep it alive, but it wont fully recover.

You've done an excellent job... the cover.. the fan... the thinning.. the more air flow the better.. looking good!

What strains are you running? I'm up the road from you in Albany. My girls were not under cover and were suffering from bud rot, and are now in various stages of cure. Good Luck with the finish!

Your set up looks good and the girls are close..congrats. One word of caution, watch for condensation under your plastic. I did the same as you a couple grows back pumping warm air into a hoop house, made it sweat like crazy at night. Had to set up another cover of plastic as an insulator.

All four of these girls are Purple Chemdawg clones. I checked this morning, and there seems to be enough airflow to keep the condensation down. Looks pretty dry under there!

Update, guys.
They are still dry. The cover has held up to the wind and rain. The mantis, Al, is still there. I haven't found any bugs or mold. I haven't given them nutes in a while... shouldn't they be yellowing by now? I was thinking of taking them down on Monday or Tuesday, but I'm wondering if I should wait if the weather isn't getting to them...??? Thanks again.

This is the only problem area and it's just the leaf tips.
