New learning for me, been buying Can 33's on ebay, noticed both the 33's and the 66 appears to have been opened and possibly recharged , I guess you get what you pay for. So based on that I took two older 33's cut about a 5 inch whole in the bottom and connected them together, voila a working 66 with double the capability as the 33.

Hell yea they were open I guess!
That hash is still wet so I put it in the fridge to finish the dry till I press it.

I feel the same way, like to understand things, but lately finding folks feel we are questioning what they do not why and what drove them to doing that vs. . There are several places on can no longer visit because I questioned why they did something(sometimes while yelling), in my case its older age.

You certainly didnt offend me flaming pie. I got thick skin! I am here to learn, and having those documents man, that made a huge difference. I picked up green cure, mixed and sprayed it on every plant. I know the PM is established on those 3 plants, do you think there is saving them? or is this a situation I need to cut and cut my loses? I have never had PM Like this before...occasionally see it on a few leaves, but never on all these. Funny thing is, this is first cycle with a dehumidifier.

For those that have used that stuff green cure, does it really knock pm down? is it effective enough to be able to keep the plants up another week or should I just be thinking chop?

I've never used it but I have used Potassium Carbonate and it worked great. I'm guessing it should work the same since it's 85% Potassium carbonate but I can't say for sure.

^good read on powdery mildew. Try not to research much on cannabis sites for information on plants. Or at the very least cross check the information with a scientific article/gardening article. The unfortunate side affect of cannabis being illegal is the mass spread of misinformation.
Powdery mildew travels in spore form to land on a living host and then draws nutrients from the epidermal layer of plant tissue to create more spores. It is everywhere outside, inside and on your clothes walls etc.
The only way to fight them is to make their home ( the host plants' epidermis) inhabitable. Some people will say that PM is inside the plant (systemic) . However the spores never invade further than the epidermis. They do not travel through the plant like water or gases do. The only form of travel for powdery mildew is A) releasing spores to travel by wind or B) spreading out with mycelium (threads) on the surface of the plant tissue.

Powdery mildew can survive on dead plant material in a dormant state as well. The spores are always around just dormant and waiting to land on a dry leaf with a high ambient humidity. So it is always important to dispose of debris/trimmings.
Your plants look to be at the harvest point. I would identify the plants that are infected and those that are not. (some strains have a high resistance to PM and other molds) Taking pictures with the lights off will help you close in on the worst plants.
If you can get another spray in before the harvest (and you are sure that your ambient humidity is low enough 35-40%) I would do that.
After spraying (and killing all that it contacts) I would manually remove all infected material. Leaves, stems, and any buds that have sugar leaves infected. Dispose of them. If you see infected sugar leaves it is likely that the mycellium threads have grown into the bud.
Increase airflow by removing any foliage against the tent wall, within the dense center of the plant, and any leaves that are in tight quarters with each other.
Spray down the plants again until there is runoff (dripping). Do not be afraid to mist the buds. It will not affect the flavor or hurt the trichomes as long as you are using the correct dosage. Try to get the plant from the underside as well. Both sides of the leaves. It is important to get all the angles.
I use 1 small scoop to 250cc. Follow the instructions on the jar and do not exceed the 2 tbsp per gallon.
While harvesting, take time (before setting aside to dry) to examine the buds under a loupe. Look for thread like fuzz. If a bud is suspect, dispose of it.
I'm not going to sugar coat it. This will hurt your harvest. I lost a good third to powdery mildew 4 grows back. My circulation fans had been plugged into the wrong side of the timer and was off during the dark cycle.
In the future, air circulation and a preventative spray down once a week will give you peace of mind. You may want to set up a few extra hygrometers to see if there are any areas of high humidity in your tent or directly outside of your passive air intakes. I discovered my basement window was leaking air and sealed that up tight as a virgin's ass with great stuff. You may find a surprise too.
Plants leaning against the side of the tent (some tents sink in alot when closed. Look at your plants through the viewing window.), leaning against eachother or just dense overlap of leaves can be dangerous. Try to stake or tie up colas so they don't touch the sides of the tent. Trim leaves on the outside of the tent.
Keep good airflow above and below your canopy. Fans blowing across a leaf surface will lower the humidity and temperature around that leaf. An extra fan uses very little electricity. 3-5 bucks a month in electricity is nothing compared to a loss of a third of your harvest.
After harvest and clearing out your tent it would probably be a good idea to spray everything down with 3% hydrogen peroxide. Unplug your fans and mist them as well. (give them half a day to dry out) It also couldn't hurt to throw your carbon filter cover in the washer.
Low humidity, good air flow and preventative sprays. If the environment is hostile to Powdery Mildew, it will not grow.

Sorry it took me so long. I was thinking carefully and trying to cite my sources. Still looking for that greenhouse airflow article..
Edit: I think i found it.

No problem. I know how stressful it can be and it was a bitch to track down the correct information back then.
Just roll a joint, accept what is, and move forward.
If you ever need help or advice in the future use the @ tag and I will see it.

@giggles26 I'm thinking about getting a portable ac...I have a question though and this is to anyone who knows...
Should I put the ac in the tent and have the exhaust going out one of the vent holes or have the ac out the tent blowing cold air in the room the tent is inside ?

Both will work if you put it in the tent you can add co2 more effectively.
