"rapid" Necrosis...need Help

[Weedthefack]

Alright, been reading here for quite a while now, always found what I was looking for - but now I'm not so sure.

Is it rust fungus, is it calcium deficiency, is it something else?
Found rust brown spots on a couple of leaves, looked like some sort of residue from spray. That was 2 days ago. Now those leaves and a bit of the stem look like on the pictures. It's only 3 to 4 leaves on a couple plants (dosido), some close to each other, some not with healthy plants in between. Only on leaves on medium height, not on new growth, both facing the sun and shaded.
Growing organic in soil, weather has been warm and dry, ph

around 6.7.

hey you know it got my curiousity up last year,i was thinking grubs down in the soil,so dug it up,man i had grubs under them plants as big as a toe,never figured it out,i got some desert camo and put it over my plants last year to get them to finish,they were doing same shit,so first thought was ph swing,so i got one them canopy you buy at a sporting good store,had over the babies swimming pool until the hurricane wanted it instead,but put that camo over the thing and stood it up over 3 pretty good size bushes,went back to feeding and watering with condensation water from ac unit,bettween the shade and ro water they finished out and i got plenty of great tiger strip seeds,sure thought i was gonna loose them,had another hurricane tried to take the damn canopy again,bent my male over pretty good but he still dusted there ass good,check your ph in them spots were your having problems,cause if it is dieses you sure dont want top let it spread,if iut is a diease problally better to harvest all them so it dont screw your soil up for the coming years if you

Yeah, that's what I thought first (Or at least what I want it to be) but what made me question that is that there are no spots on the young leaves and there is no yellowing either
