Cat piss? Not the strain....

@Amandus hi mate im not so sure a cat could piss that high?? lol but seriously some type of liquid has been sprayed or dripped onto those leaves resulting in the spotting I also noticed some almost perfect holes in the leaves which be from leaf miners

High Amandus, It looks like these leaves are sunburned.The leaves were probably moist during a hot moment of the day. A few years ago I experienced the same kind of problem with my outdoor grow 1 day after watering the plants during noon. The bottom leaves that became wet from wattering with a hose had the same kind of sunburned spots on it. Happy Growing! 😋

question, are your plants under a tree or tall shrub or something? does it rain in the morning and get real sunny and hot quickly?

It is an older male cat. I'm mainly looking to eliminate it as a possible cause. Not threatening the crop, but I'd prefer pee free bud.

Yay go mouse trying to get votes with a dumb disclaimer *** some people just like to help and not answer blah blah nutrient lecture blaaaah. I'm not bothering,I don't need a bong 🤣

Could be Septoria leaf spot. I find potassium bicarbonate works well as a fungicide. 1tbsp per gallon. I find it usually gets spread from a nearby tree that is infected. But it could be from anywhere as fungus spots can travel a long way.

Some sort of burrowing mite or other visitor. Others will come, they know the correct squirty squirty stuff to deal with it and protect from now on,I bet you can even use it flowering,hell tip it in a water bong it's so good. Or something. Probably a grumpy...

Not just this one plant, photos from all three plants one next to another... made a fence today, soaked in vinegar.
