Strange leaf spots, seems to be spreading around the room. Tobacco mosaic?

Got you. What magnification do you think is good to see what may be there

 

[Captspaulding]

Nah they got it outdoors in dusk and was shaded also fully

Well, calcium, or you have some visitors……

as much as you got..
look on underside of leaves, on top of medium, look everywhere

You probably can use you phone cam, zoom way in, snap some photos, then zoom in again in the album. It works.

Pull a fan leaf off and take it over to a table with good lighting and examine it.10x might get you by. 20 or 30 would be better. diagnosing this stuff is about eliminating as many causes as possible. Pests are a cause that is pretty easy to eliminate. So it’s a good place to start. Then it is on to the complicated stuff.

 

[billoddy66]

Had a look under 30x nothing I could see pest wise!

 

[Captspaulding]

Well that’s leaves 1 thing…..cal mag.

Yeah definitely want it not to be this way but due to space and ACS stopping along the way have to have veg outside for now

The ones with the netting aren't in flower not yet no. Will be soon was plan.

Do you think the three fingers could also be caused by heat stress or nah?

I'll get onto a 100x lens

Would be keen to see if similar

Honestly to me it looks like leaf septoria.
A fungus that lies dormant in a plant and is activated by high humidity and heat. I had it once look it up fellas I hope it helps.

Good luck

Hard to see the damage to the leaf on the top but zoomed in you can see the silvery spots I mentioned earlier

For these (thrips) , in veg, I used captain jacks deadbug 2 applications and gone

This is with a Wi-Fi microscope from Amazon ($20) at about 60x magnification, should have bumped it up for a better pic has capability of 500x lol, was just searching and happened to see them and grabbed a screenshot

It was how quickly it happened, and the environment at the time that brought me to that conclusion. But no? Hmmm, interesting.

Yeah pretty sure there's thrips in there but they've been there a while and never had the orange/brown spots. They look like erosion close up

 

[billoddy66]

Had a look under 90x just now with a light couldn't see anything on these leaves that looks like a pest
