whats wrong with leaves

What causes this

when grow nutrients are changed to bloom nutrients
late flower plants shed their lower leaves when no longer needed. my veggies and fruits do the same outdoors
there are a dozen other things that could cause a leaf to stop functioning, those two are common

The dots are necrosis with lesser damage surrounding it. I've never had cannabis get that bad. I've had two roses go that far. There's a huge list of the fungus types that show up. Being cannabis you can't use copper or a potassium base fungicide. Eagle 20 is also a huge no no. They all make it non-smokable.

I have a seedling showing rust spots. Another type of fungus. I'm going to treat it using Bacillus amyloliquefaciens strain D747*. "Southern Agriculture Garden Safe Fungicide". The same strain of bacteria that Bayer uses in their organic fungicide...but those guys are Monsanto a$$holes.

why is it always the oldest non functioning leaf that gets this. I've seen it on a sloppy clone, didnt amount to anything, I cut off the dying leaf and moved on. it vegged and flowered with no more. is it like a dying vegetable matter growing fungus on the dead material, like yellow leaf in a wet tray?

Damn Damn Damn. I already ordered the fungicide.

Then I looked on the back of a mini jug of Botanicare Hydroguard. I have laying around from the hydro days. Don't remember buying it. Still sealed.

Wouldn't you know it. It's the same #@$X! bacteria I just ordered. Bacillus amyloliquefaciens, 38%. This Damn stuff is probably three times the concentration.

Shit. Well at least I don't have wait to apply it. I'd add this stuff to a sprayer. Calls for 2ml a gallon for hydro. Ill mix it at 1ml to 1.5 liter of water. Spray muh' plants.

Looks similar to a ph issue. Have you had any PH swings ?
