Are you in soil or are you doing hydro? In soil adding certain bacillus species can help prevent or kill fusarium. Make sure there's enough aeration too.
Coco. Issue with clones is gaping wound from cloning. Things like bacillus or trichoderma colonize the roots and prevent, which helps later in growth.

Hi, I went out for a month and when I came back all my plants had this

It starts as small dots

and finally it spreads all over the leaf, ending up drying it

It doesn't look like botrytis because there is no budrot and it doesn't start with the flowers, however I am in the subtropical rainy season and as the symptoms get closer to the sugar leaves drying them out, I'm sure there will be budrot.

So can you help me identify it? Is it a fungus or a bug? Can I still do something or would it have to be a premature harvest?

Could be leaf septoria or ca defiency. Is new or old growth more affected? If it's new growth than it's ca but the full affected leag look like septoria

This one leaf stood out during the harvest.
Are the spheres the fruiting bodies of a mushroom?

I'm not sure either, but the other trichs are cloudy to milky and only a few are amber. Their trunk is not that thin either.

Do you have any tomato plants and have they been affected ?
Couple of weed plants had the same progression as yours last year and it seemed to spread from the toms by contact , cutting the leaves 20mm ahead of the advancing mould helped and the buds were not as badly moulded as i feared.
Thought i had a defficientsy till i noticed it on the toms.

Farm nearby had a field of sweetcorn destroyed by it so it probably spread from there , said it was blight but forget the specific name he said.

starts with old leaves my friend and expands from there, any advice, or you think is to late?
Sounds like septoria when it's the older leaf. The dead leaf are infectious and will spread the shit on the plant and to others.
If its doable pick every affected leaf or make an early harvest and make hash out of it.

Thats mold and maybe not the one u want to consume. Once was told that the yellow heads can be aspergillus flavus but have no confirmation for this. Thats the one that kills your liver after 20 years when f.e. eating moldy peanuts

I'm glad I discovered it and got rid of it.
I should probably check every Bud carefully for mold.

Of course, I removed everything that could endanger the harvest.
Is 3% H2O2 enough to kill the spores?
I use it to clean the surfaces and 12% is too aggressive imo.
When the tent is empty, I also use a UV lamp.

Not spraying. I have to redo the pictures. I added microscopic pictures and leaf is no longer shown. I will run ducting to vent the rooms into main house and should lower humidity in there. Have just been leaving door open.

Here are microscopic shots of the white spot and adjacent area. Need to click on link to see the leaf normal photo.

Thats residue from condensed water from the ceiling. At least that's what I reckoned when I had the exact same look in my greenhouse a few days ago and also last year in the tent when it was cold outside of it.
Edit: when I said ' same look' I was talking about the hidden photo, leaves with white chalky dots only on the leaf tips.
Get humidity down and/or temperature of the walls and ceiling up.
Otherwise water drops can land in the flowers and cause budrot.
Second edit: lol, this condensation happens most probably at night, when the lights are off.

I had a gnat infestation due to reusing coco coir. To solve the problem, I cut clones, uprooted the plant, washed the roots, and transplanted it into fresh, unused coco coir.
