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

No bug sightings with a 90x, then it’s probably
Something else. Now after u assert yourself on the bug issue the next probability needs to b eliminated. Unless your plants have no calcium I’d look into the septoria

 

[GNick55]

ya definitely not leaf septoria.,

Ive only been growing for a couple years, but with a lack of bugs i would go with it being some type of burn from the foliar spray.

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

Captains jacks is amazing. Always does the trick.

Agreed 100%

 

[billoddy66]

I'm finding more leaves going that way slowly but surely. Some the dots connect a lot. Leaning toward calcium deficiency

Coco wasnt buffered and bought cheap from a non hydro shop

What do you guys reckon

Stil can't see any pests on there

 

[billoddy66]

Nah bad water in Thailand from tap

Ro broke and haven't haven't had time
Ppm is 100ish out tap

Are you buffering your coco?

 

[billoddy66]

Are you buffering your coco?

I came here to help and have discovered no

 

[Stokes]

If you dont buffer your coco it will leech all the calmag from your feed before the roots get a shot at it. Those last pics are clear calcium and magnesium deficiencies

100 ppm is considered kinda hard, in the state I am it’s 40 ppm, and that consist of cal/ mag and other micros and that usually does it along with the nutes I add that also has c/m, unless it’s a c/m hungry plant I don’t add extra.
U may be dealing with a lock out( idk yet as I don’t know your nutes or schedule)

 

[PopPop67]

Yep low pH and low calmag all day

It becomes easier to tell the cause when it gets worse but it starts with little yellow to Grey dots
