I think we figured it our today...downy mildew. or downy mold. its a water borne pathagen, a mold. after a phone call to maril I dosed with 7.5 ml/gal of physan-20. fingers crossed. will update with progress. this is from not keeping my RO rez, the one feeding the humidifiers, sterile. now I will.

So what ever come of this did the physan-20 work ?

You spilling nutrients on them when feeding? Could be the cause of the mold. Hopefully you can get it squared away

No it was downy mildew from the humidifiers as mentioned.

Glad to here you cleared things up, but thats crazy how your plants got infected from your humidifiers and caused that much damage to 1 leaf. Now I'm gonna clean my humidifier every refill like the directions suggest because I never did before.

I am from the US and it seems like you guys have alot of problems with your grow. The first thing i think you need to understand is that cannabis is a weed, REALLY. So you don't really need to over nute it causing necrotic leaves which is dead leaf flesh. once its dead, its dead. I grow regular and auto-flower but have stuck with the auto flower. Currently I have Blue OG fem. and Dinafem cheese both of which I have given no nutes, like my last grow. I gave it nutes and had yellowing problems. Not so this time, even with a flush the weed tasted like nutes. I have plucked a bud off the cheese plant to test the flavor and i have to say WOW, no nutes works for me. the high is major and body. i use a reuglar organic soil .21-..07-.14. I have found that a slow release nitrogen soil works best. Because i use this soil I have had no problems with knats, mites or anything that hurts that plants.

AC units house mold because of the freon used to cause the cooling. you should keep them set to about 76 this way you don't freeze your leaves out.

Not sure if u read the previous posts but this was a airborne mold not nute burn.

Just so you know AS, this isn't true. They house mold because of dirty moist filters and standing water.

I think if you understand what freon does then you would understand that the condensation is caused by the cooling process which is done at the freon level. Thus causing standing water and bacteria build up.

Sup AS, Freon is brand name for R-22. I agree that standing water caused from the evaporator coil hitting the dewpoint and not properly draining or evaporating from the discharge line, is a major cause of bacteria/mold. Especially for an AC working on plants with that extra humidity involved. But if you change/clean your filter and make sure your unit has no standing water (I drilled mine near the discharge line and put a bucket underneath.) there should be not bacteria/mold issues.
I'm just saying that someone could think if they buy an 410a system, then it's not 'Freon' so it won't mold. When you say Freon, you mean Refrigerant. I would also recommend buying foaming evaporator coil cleaner, it will disinfect and clean your coils.
