LuckyAcres, have, or can, You see any 'critters'? Are the spots growing in size or are they static? I have seen some viral infections (in other plants) that look similar to what You have, You might try washing a leaf with an antimicrobial solution (mild dish soap) or get something specific for viral and bacterial infestations from a garden store.
Good luck

Hey dw2, thank for the input. First spotted it last week I think, tiny specs on a couple leaves, thought of water drops after feeding, dismissed it. Went in for a check today and noticed this leaf and a couple others. Whatever it is it's not moving fast. No time today for looking with loupe, but nothing seems moving at all. Virus would be my second guess. They did have fungus gnats bad and i know those bastards carry viruses sometimes, maybe it's a leftover. I'll remove all infected leaves tonight and monitor. Next feeding might just be phed water and hydrogen peroxide to clean that shit up real good!

alright so I'm waiting till lights on at 8pm to check it out, 2.5hrs.
Condidering the past fungus gnats infestation it is safe to assume the bastards have left crap behind like viruses.
My questions to you guys, would H2OO kill a virus? Would H2OO kill left over gnats? Understanding fully that using H2OO is pretty close to total sterilization of the soil.
i also have a bacterial fungicide called actinovate, can be used as a drench, amri certified, need check on label later for target list. Works great as spray for powdery mildew.

Viruses insert there own dna into the host plants cells and once infected cannot be killed by any type of cleaning or h2o2. One thing you.need to be careful with is your tools you use on infected plants can transfer the virus to non infected plants so should be sterilized after use

Thanks all for the input.
inspection is done. I eliminated bugs out of the equation.
I found the ground zero plant but all 8 scrogged had some signs from 1 to maybe 8 leaves affected per plant. Early onset still. I removed them. Nothing on the 3 plants at the end or in the veg room. thinking something got passed on within the scrog lot during a pruning session back in early veg days. can't really separate them all.
septoria could be it but everyone mentions it's a post flowering fungus, but no flip yet.
so I don't know folks, maybe a blight of some sorts, a fungus hopefully...
gonna go stare at the google now and find a match and a remedy.

Just got done reading rosenthal chapter on septoria and no mention of post flowering conditions needed. So I'm going with that for now, can't find anything else that matches. 1 treatment suggested is neem oil, done deal! Professor Green was on it! Thanks!
