It started off with one plant having slight markings on the leaves and then curling downward with some leaves browning at tips. This plant despite being under 18 hours of light began flowering. My plants in the other room (different genetics) that have the same soil, light schedule and watering routine are looking healthy. However there were some clones that were near this sick plant also started showing the same signs (markings and leaf curl) a couple days later. Upon close inspection numerous times I see no insects of any kind. I am used to treating spider mites, aphids no problem but none to be seen. First photo is og sick plant the second two are from the clones.
Leaf curl, markings, spread to clones as well

A lot to read. Is ph in check with calibrated meter? Always ph first because if not good , nothing is good
I always recommend folks get the basics, ppm meter/ph meter (or liquid ph tester) take your time and keep it simple. Welcome to RIU
keep us posted and happy growing

Totally over watered. Let your soil dry out, they'll perk right back up.

Can you post a pic of the whole plant/s?
That scarring looks like thrip damage. The curled necrotic leaves could be a lot things but its likely something going on in the rootzone.
More info is needed before anyone can really give you an educated guess.

I been getting similar symptoms at first I thought it was russet mites but after close inspections with 100-250x microscope I couldn't find a single mite. I'm starting to to think it's some kinda virus, bacteria or fungi.
Thanks - as far as overwatering the main plant may have been overwatered at one point but the clones were not. The main plant seems to have root issues I agree based on how slowly it dries out compared to the healthy plants. I also wondered about thrips or mites and couldn’t find any with my 30x magnifying glass. They are living in a humid basement that mold issues, temp around 70. I’ve got a fan running. One of the clones is doing worse than the others, new pic attached and the og plant has a new symptom that almost looks like a deficiency- new pic also attached. I’ll take a pic of the entire og plant when I get home tomorrow.

Thats what I am wondering too at this point- some kind of virus. Unfortunately I have no experiences diagnosing or treating viruses in plants.
Additionally I can’t rule out some sort of nutrition issue as playing a role as the symptoms began after I gave the plants some compost and half dose “dino grow” liquid nutrients. I gave these nutrients because the leaves showed slight signs of deficiencies.
Do you mean broad mites? I was worried about that. I think I’ll try to spray down all the plants with neem oil.
