Hi, am not sure what i have here. I have been pretty light in the nuts, never going above the minimal recommendation from the producer. and epsom salt between 1/4 and 1/2 tsp per gallon every couple weeks.

1 week ago, y changed from a 9-4-8 veg to a 4-8-9 flower nut (1ml/L), with only water between. The last veg i used 2ml/L, but i have been using 1ml/L most of the time.
2 days after i change to flower nut, i start to notice some yellowing with brown spots in fan leaves, in 2 northern light autos, and one start to lose some green to lime and some brown corners and spots in some of the lime leaves. so i figured it was some N deficiency, maybe they weren't ready to switch nut, so i wait to the next watering (yesterday), and i used 2ml/L of veg, and only in case 1ml/L of a root stimulant with micro (boron, zinc, etc) and a 1/2 tsp per gallon of epsom salt.

today i wake up, and they got real bad... what was something here and there now is everywhere.
i took some pics. Any idea? could be an excess? i have been pretty mild though.

it could be, but i'm sure i have not overwatered, the humidity is around 60%, but it is a little cold, around 68f. and i have a third plant in full flowering that don't have this problem... and have been receiving the same amount of water.

Looks like classic, but really advanced, calcium deficiency. Is anything you're using a calcium source? Could be lockout from your ph being off.

I've never dealt with any funguses other than pm and botrytis in outdoor plants so I can't say for sure that it isn't some other fungus but that really looks like advanced calcium deficiency.

i'm not sure, i'm using tap water with at least 400mg/l of ca+2, and i regulate ph between 6.2 and 6.8, chlorine is a little high at 250mg/l, but i wait at least 2 day in an open bottle to use it.

the mold is a symptom of abuse, lack of controls coupled with over feeding.
those plants are not worth one more minute of electricity, they will not produce any usable bud, they are hit, kaput, dead,
never can be repaired, it is over, RIP.

plants use different amounts of water.
when you water a new dry container you only add 1/4 the dirt volume in water. you dont add this again until the container feels new and dry again, repeat, no matter the day or time of week. the plant grows more in dryer soil than it does in wetter soil.
you are overdosing them with laxative additives. stop the epsom salts. did you notice an epsom salt deficiency?
you need to choose a quality nutrient system made for this purpose and stick to the directions. they know more than you do about what your plants need and when. dont confuse thinking with feeling. dont feel like adding anything because you feel they need it.

highly suggested you read ed rosenthals grow bible before wasting anymore money on this hobby. you'll thank me when done, I did it in a weekend on the deck. prolly has vids for non readers. good luck

I'm still not completely convinced it's mold. If it were so advanced to be affecting the whole plant like that wouldn't there be some visible patches of mold?

that could be, or maybe: https://www.alchimiaweb.com/blogen/alternaria-cannabis-crop/

im sure it isn't over watering or overfeeding, and the humidity is in check, the temp is a little cold around 60f, but it isn't that cold. the spreading has stop for the moment, she looks the same as yesterday, so could have been a mixture of deficiencies, but it is strange. i think it is some type of pest, but i cant figure out, what.

i never had something so quick, and explosive like this, in 3 days it grow from a couple yellow leaves to this monstrosity.

there is no sense in wondering if mold can grow on dying dead leaves. of course it can and it will.
the mold is not what caused your plants demise, your habits are. the mold is tyring to cover your ass and consume the dying plants before anyone else sees them

I didn't say that mold can't grow on dead leaves. I said that it seems unlikely to be mold if the plant is affected head to.for by whatever is going a d there doesn't seem to be any actually visible mold. And a final thing you should take note of, I'm not the OP of this thread. These aren't my plants. I've never had fusarium. You have no clue about what my habits or procedures in my gardens are. Oh, and I also didn't say thing about mold not being able to grow on dead leaves.

I can see mold on ops plants clearly. others can see the very same molds, same type of mold even. consider this the bible.
the mold is not the cause of his issues, it is a symptom that perhaps flourished when leaves began to die, more likely though been there through the whole cycle, and now has blossomed.

Maybe it's just the quality of the pics, or the fact that I haven't dealt with fusarium, like I've said, but those spots on the leaves also look like the necrotic spots that I'd expect to see from calcium deficiency. The deal breaker for me is that it spread to this in three days from the initial onset so it's obviously not a deficiency.

necrotic spots happening I think because thats what happens during death, including going through all of the deficiencies as it dies.
it does have a calcium deficiency, the roots are no longer up taking nutrients, the leaves are no longer photosynthesizing .

If the spots are the mold than the spots are the fungal fruiting bodies. There's probably a good mix of ones that started as necrosis and/or mold first though.
