Powder Mildew - Week 5

[MrBomDiggitty]

60 plants, aeroponics, 4 rows of 12. The rows werewere kept too close and now the low leaves have PM on all plants.

About to use the sulfer burner, but I'm hesitant. Maybe try to spray just the leaves with Serenade?

If anyone could suggest a better alternative which would spare the quality of the nug, let me know.

week 5 on an 8+ week strain and you can still use the burner imo. if you have one already no money lost. BUT......if you want to nail it good try the zone and penetrator combo. it works amazingly well and smells way better than that serenade crap. costs $$ though. but so does a burner if you dont have one, but the burner is an investment.

Try doing a lacto bacili culture. saved my ass this outdoor season.. You will have a lot of work tho cleaning all affected leaves but it works like a charm!!

Hope it works out fine for you and the plants.

why not use hydrogen peroxide?

I like SM90

Works well. stop using it about 2 weeks before you harvest, you spray it for three days and you are done

Will discolor the hairs a bit, but I can never taste it

Whichever you decide to use, be sure to spray all the way inside the plant...not just leafs-- PM also builds up in the crook of branches...where they come out of nodes--

we had had some pm, the best thing is Dutch master's Zone and Penetrator.... i'm gonna have to find the formula but it works..... we tried the sulfur burner and all it does is make it go away for lil bit, but the zone and penatrator work amazing, it's all gone and my ladies look great

check out the threads posted by Chimera about pm, there's one called actually killing powdery mildew, he gives you the formulas for the ZP

zone/penetrator. never seen anything like it. i went the long route to get to it. 10ml/gal zone and penetrator according to the bottle. dip clones or spray thoroughly. i had it bad. one treatment on my clones and i haven't seen it at all....mind you i live in a cold (now) low humidity climate.

 

[LittleMissGrow]

the zone and penetrator do work... like i said we tried it and it worked, we didn;t have humidity problems... we were just sold some dirty ladies.... but it worked.... after dippping about 2-3 days later we rinsed ours and after the rinse the boomed like crazy

I have used neem oil up until about week 3-4, neem really kills PM, but I'm not sure if week 5 is too late, anyone else use it this late? In the future I would start hitting them with neem as early and regularly as possible to prevent PM in the first place. PM is a pita to deal with, I know how it goes.

So... a quick update and new question:

Does PM always come in spots, or can it appear centralized around the cola? From a distance the nugs looks fat/frosty. Up close, the "frostiness" is more powdery than shiny, like trichomes and talks appear.

A special foliar was also applied, but I forget which.

I was asking for a friend with no computer access. I think he tripped out cuause they looked bomdiggitty to me. sorry no pics
