Powder Mildew

How long after a plant has been infected with PM will u start to c sings of the plant being infected? I don't have a mother room. So I take my clones straight from my plants that I am putting into flower but this time when I went to take clones I c some of the plants have PM I would say only about 4 plants have it out of 12 from my visual and I would say about 1% of the plant is coved and the few spots are very light u almost can't c with the nak eye. So I guess my second question would b how safe is it to clone of the plants that I c nothing on? Or is it a for sure bet the clones will have PM the plants are 30 days old in veg and ready to flower but they are 45 day ole in total 15 days pre veg.

Spray them with one teaspoon plus a pinch of baking soda, per quart of water. Spray them every two days for 6 or 8 days. That should stop it. Spray everything with it even fans. Then flower. Do it again in two weeks and again twocweeks after. Then again if it starts coming back in the last month of flower. You should be fine for less than a buck. And yes, spray the clones too, they will definitely have it as well.

If your plants have P.m then your plants have pm. It will never go away as it is incurable with the crap products that we have at our disposal. Your plants were weak to begin with this is why they have P.m.. Let them finish then start over but before you do you must sanitize everything. EVERYTHING!!!! Or you will get it again and again ect. Pm is systemic, its there even if you think you sprayed it off. Don't take clones from sick plants with pm.

Ive stopped it before. With a plant i cloned for four grows in a row. For the first couple grows with it i sprayed the clones and then sprayed a couple times in veg. Gone by round three. But yes, i washed out my tent liner in the tub and washed out the whole tent by hand. Used fresh dirt and ran the pots and clone trays through the dish washer. And cleaned my clone domes between uses. After that it was just getting enough airflow to get the humidity off the leaves and keeping the rh down. Baking soda works great.

Use the spray mentioned by @Alienwidow and add 150 ppm of 3% H2O2 to your feedings. It's everywhere outdoor where I live and impossible to keep it out of the grow room without unmanageable practices, like showering and stripping down every time I'd walk into my grow rooms. Spray them and add the feedings in veg and they'll be fine. It will attack any plant, not just weak one's. The main difference whether it can be managed or even completely eradicated is genetics/strain/pheno's, some and particularly indica/indica-dom strains are susceptible to it while others are almost immune. If you're lucky it was on the clones you got and not rampant in your area. I'd never had to deal with it until I moved to where I'm living about 3 years ago, some garden bushes in the area are white by the time fall comes around, nasty shit, but manageable.

Add one crushed 325mg bayer aspirin tablet to one gallon of water and use once weekly untill week 4-5 of bloom.
This will not cure pm. But it will boost your plants immune system and improve its ability to ward off pm.

Best of luck.
Peace
