Please confirm symptoms

[Stinky Snid]

Hey all, is this leaf miners? It's my best guess at the moment it doesn't look like anything I've seen before. And the incredible thing which may confirm leaf miners. Since their secretion attracts ants. I saw an ant in one of my pots. It's the middle of winter where the hell did an ant come from.

Using promix Bx, with coco and worm castings. 18/6 lights cfl/led, first nutes were 5 days ago and yesterday
Grow/micro/bloom and voodoo +b52 sibling is same age same food and has no symptoms like this.

Please advise, thank you

Prob overwatering sitting in wet soil

Does look like something is eating your lady, is there any other signs of bugs? Could be a calcium def. It's not an overwatering issue that's for sure.

I washed her with some food grade bug killer. And it's continuing, I cut away the dead parts and it's still spreading. It's only one plant out 6 so I don't think it's bugs. I've looked high and low all over the cannaweb and kind find anything that look like that without turning yellow or brown first. Im thinking either a genetic flaw or some sort of blight...
