Ok, one more time for powder mold.....what is the formula for 29 % Porixcide and water solution? I am 1 week from harvest and today I noticed small traces of it. Guess I could spray 10 % milk and 90% water, just wondering how to deal with this pest!

Lemon Juice & pure water. 1 part juice to 3 parts water. Organic and effective. Works by lowering Ph to a level to low for the PM to survive. Plants love it and no left over smell or taste to speak of in the buds.

What is considered "pure water"? I have RO water with 6.1 ph naturally as it comes out of the tap. Do I lower the ph and use that? Anyone?

3 Parts RO to 1 part Juice. RO/Distilled is preferred as tap water will leave cal-mag and other minerals behind on the leaves.

Learned from Subcools weed nerd show. Some old timer on there was boasting about it, but I have heard of using Ph down to accomplish the same thing, lemon juice is just as effective and 100% natural organic.

lemon juice or microbe tea will do the trick (or fresh milk) but if you are close to harvest use lemon juice. The tea takes time to take hold.

BTW Weednerd is a great resource for information. Although Subcool is an organic soil guy, the tips he gives out are useful to anyone. You can watch weednerd via youtube. I really enjoyed the garden of weeden vids. (might as well check out Jorge's channel too)

Milk will only work if it is unpasteurized. The stuff at the grocery store is useless.

I just had a bit of a PM battle a couple weeks ago...Serenade is what I used, cheap (about 8 bucks) and also OMRI listed so it is organic. Says it can be used up until the day of harvest however I don't think that I would use it that close to harvest. So far I've had good results PM has been gone for a couple weeks and all seems good.

yea sorry, I grew up on a farm. To me fresh means straight out the titty. I agree that unpasteurized is a less ambiguous term and avoids mistakes.
