What do ya'll think? These pictures were taken on day 34 of flower. Roughly 1/4 of my plants have similar leaf blotchieness.

Looks more like a minor Ph issue more than a deficiency. TMV, naa that is a questionable subject in regards to this being transmitted to cannabis as it is with tobacco and other plants. Been growing out tobacco and herb together for years and never have I seen Tobacco Mosaic Virus effect anything other than tobacco.

Outdoor grower here. Don't know yr variety. might simply be Senescence ...
I had some revegged plants from outdoors that got it first, hence why i was thinking TMV. No old clones.
It looks like potassium deficiency during flowering. K is for bigger branches and stems, and when the plants stack (grow little branches on the buds) they need more K. And they like more space for roots too.
Plus, K is generallly associated with strong and healthy plants. So even if it is a virus, it still may help.
Also, I don't know how the airflow is, it is hard to tell from those pictures.
Top picture does look like a K issue I agree. However the bottoms does not. Veg plants in nearby room have it (bottom picture blotchiness) to a lesser extent as well.
never heard of tmv had to look it up. sometimes on outdoor i would get this purpling on leaf that would slow spread and stunt that part of the branch never knew what was

Just this guy, ya know?
TMV might not be the specific mosaic virus attacking canabis plants, but it's been very well documented for like 20 years the existence of at least one strain of hemp mosaic virus.

I've had this as well, It's debated weather it's phos or virus related. I believe in the later. Some of my re-vegged plants actually had it.
