Cure for Powdery mildew in flowering?

[pseudostelariae]

I threw my whole crop away when i got spider mites. Then i did some research on why i got them
1) clones from friends
2) pets in house
3) not changing clothes after mowing the lawn... or being in nature
4) house plants

Which rule did you break? Probably number 1. I broke number 4. I took a plant in the house ....and they found the way to the plants several rooms away. Spider mites hate onions. Anything in the onion family and they vacate.

mainly number 1 but really all of them. i made it to harvest and cropped a measly half lb under 1200w. bleached the shit out of the tent and brought some new plants in and still....PM and spider mites showed up a week later.

i added a new fan for extra air movement and got a pyrethrin based 'take down' spray i'm alternating with azamax but it's getting to the point where i'm about ready to just go with eagle20 and floramite on every plant in my house. actinivate sounds promising, maybe i'll work that into a preventative schedule once i get this under control.

i cant believe no one has mentioned mkp or mono potassium phosphate / 0 -50-30 /
they sale it in bulk at kelp for less and other places it is a powerfull bloom booster it can be used through out flowering and will kill pm dead in it's tracks, be sure to correct your humidity levels and ensure proper airflow you can also buy MAP and some B-1 and mix your own MOAB for a fraction of the price

Reduce RH to less then 40%
Increase light levels.
You can try GreenCure it is not a poison like other Mildew cures. I have not used it.
Stop using PM susceptible clones.

I kept big clones overwinted veg in the ground in a greenhouse with really the minimum light levels to keep them veg, every winter the PM susceptible would get mildew on their lower big leaves, I would take clones from them in spring and the PM would dissapear, sometimes I got a little tiny bit at autumn at the end of flowering. I kept the clones around anyway for different reasons, but hesitated to use them for breeding.

The real way to cure PM is to stop using any clone that is susceptible to PM, that is most Indicas WLD, and many of the Indica/Sativa WLD/NLD hybrids. People who use PM susceptible plants, clone them and use them as parents to make new seed varieties that are getting PM, any wonder why?

Said it before, i'll say it again, high PH water is perfect for destroying mold and preventing its return on living plants, and in the end of flower it can help color your pistols.

I of course recommend the natural stuff, earth juice, mad farmer, green cure (overpriced earth juice), etc, get the PH nice and high, at least 10.

High PH water on the plant or used for watering?
I ask because water on the plants will increase the RH and just make more problems...
I say the real cure is to stop using PM clones.


PS did you know that you can strip away all of the added alterations to your photo, do you want me to post it to you?

what if you're outdoor and there's no way to bring the humidity down? it's been a few days with RH 50% during the day and 90% at night. looks like it's going to warm up and dry out a bit but i have to make it to october at least, need to do something.

will high ph h20 sprayed on flowers burn the pistils? i have a mild pm situation.. i am presently picking off affected leaf. i sprayed w milstop and it knocked it back, but burned the pistils more than i would like.
