Mystery Mildew/Mold?

I need some real help diagnosing this problem. It has spread all over my veg room and is slowly defoliating and killing the leaves from the bottom up. There are visible spores on some of the top fan leaves, and the tips of the shoots are brown/rust colored. It is slowly killing my plants and clones taken from these plants will not root. I regularly cycle through imid, avid, and eagle 20 in my veg room every 30-60 days. No aphids, PM, or mites present. Some occasional fungus gnats, but mosquito dunks are used everywhere. I usually only foliar mist water with a dash of Aquashield, but have been lazy the last few weeks as its gotten hot and super dry, so I've been wetting down the plants with the hose. I'm thinking its a mildew such as black spot (septoria) or downy mildew that could of spread with unconditioned water as the main vector. It seems surprisingly resilient and is disabling my plants. Any ideas?

You can see some of the mildew's spores on the leaves in some of these pics.

I've already done foliar treatments in 48 hour intervals using:

Aquashield (heavy dose)
DM Zone + DM Saturator
generic brand copper soap spray
Greencure
Actinovate

and its still showing up and plants still have no new growth, and I'm still seeing spores on leaves.

Before anyone comments and says its a nutrient lockout/pH issue, look at my past threads and posts please. People love to belittle others with obvious answers in the infirmary and I promise you I know what the fuck I'm doing, I almost never have issues like this! It is showing up on various strains and in all stages of life, clones, seedlings, small and large vegglings, mothers, etc. It is on my plants that are in ProMix being fed organic compost teas, it is on my hydro mothers being fed GH 1-1-1 at 6.1 pH, it is on my vegglings being fed H&G AquaFlakes at 5.8 pH, and its also on my coco plants that are being fed H&G Cocos at 5.5 pH, all different additives and ppms, etc.

I have on hand some "stronger" systemic stuff that I'm not sure about using. Not sure if anyone has any recommendations on systemics or the like. But it looks like if this battle goes for the worst, I might have to break out the serious poisons. I also picked up a bottle of CEASE (1.34% B. Subtillis), which is basically just super strong Serenade. Gonna give it a shot while I'm still trying to kill it topically and/or biologically.

My buddy recommended a few products such as Heritage or chlorothalonil, but reading up on both products, they seem pretty serious, especially the Heritage. I need to step up the game on the fungicides or I'm gonna loose my genetics...WTF!?!?!
 
It's Ph lockout bro, J/K

4th pic down looks like the gray mold I have on my clone trays right now, shoulda picked them up a week ago, now it's an uphill battle. Keep me posted on what works, gotta feeling I'm gonna be treating the same thing:tiphat:

shit bro.. if its genetics at stake.. time to take some back up cuts.. if your clones wont root (due to this sickness) and you're using an ez clone type cloner.. try adding some hormex + a lil superthrive.

looks like the start of possible bud rot .. but not sure by any means.. kind of a mystery to me as well

Also I know you know your stuff, so just tossing in 2 cents.

here is a pic online I found with bud rot in early flower..

usually less common on such new growth.. buy maybe to do with foilar feeding changes?

just my guess..

Only an idea but try researching about some thing called tropical wilt disease(i think thats its name)a pal had something he called that and he said theres no cure and if its this you have to completly get rid of every thing in your grow tent, room or area and i mean every thing has to be thrown out and a whole new set up and i mean every thing you cant wash it off or serilise nothing and i mean extracter fans light reflecters tents,it wont clear it,but i hope its not that.i will try and get more info off my pal about what he had,any way good luck:tiphat:

nutrient Burn with PH lockout and mold=Time to restart

agree, however like i said.. it is very possible to salvage genetics sometimes.. even if you have to cut, veg,cut,veg,cut until the cut is healthy again..

one time I received a very unhealty cut of strawberry cough from some people who were tearing down their entire op to restart and were just gonna toss it.. it took about 6 months worth of re cutting and vegging to get the cut healthy again, but it was well worth it

very easy to get burn with Organics I use organics you can burn believe me seen it done it so on and so forth


Should be 6.5 in soil should be 5.8 for soilless mediums. If you dump 1200ppm or more it will burn or start to get to the point of burning. I dont feed anything over 1200ppm

SC, uggh.......!!! i got the same thing... i think, 4 weeks into veg i first noticed a top like the picture you took, being taken over by mold looking spores... it was getting blasted by the fan so i thought maybe just dust or something, but then noticed, little BRIGHT white specs randomly on all sorts of fan leaves... is this what you have as well?? i brought a gifted ez cloner into my room 2 weeks before i noticed... ... ugh... i used a light application of Eagle 20 right before i flipped and still, Little BRIGHT white specks, like little death stars... that's what i'm calling it because it all over my DEATHSTAR!!!! AHHH!!! lemme know if you find anything out, thanks

U PH your tea's? Madness I tell you!!!!!!

P.S.
(You shouldn't have to PH your tea's.)

Just because I measure my tea's pH doesn't mean that I actively pH it....acids or bases will kill off the great benies that the tea is cultivating.

On a rare occassion I will use some fish hydrolysate in my tea that raises my pH, so a little dash of hygrozyme and molasses straightens it out just fine...other than that...never have I pH'd a compost tea...

Oh, and yes, this is a mildew, and I managed to kill it using a systemic fungicide product called Heritage...plants look much better only 3 days after spraying. I won't flower any of the moms I sprayed, only take clones to keep the genetics and reveg new pretty moms.

I told one of your people you are welcome to another product if your system does not work...
CS knows where to get me if needed..
I'm pretty sure what we used a while back is called banner..Good on ya for not flowering until you know the product has cleared the plant..If you need some banner I'm a PM away.....
Take care.............................CC
