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.
