one plant out of 5 being eaten?

Hi do anyone have any knowledge of this its my first grow I have 5 plants in 60/40 gold label with autopots

To the problem there is one plant at the back of the tent that look to have been eaten...

My neighbour set a fire the other nite and the smell come into my tent along with a couple of gnats that appear to have gone after I removed all plants bleached tent and pure I wire mesh over the intake feed I have checked the coco and plants for any bugs with microscope and can't see anything unusual there but leaves appear to be eaten but only on one plant out of 5

I just did calibuzz caliclean method

Simmered down 3 scotch bonnets and 1 naga and used as a misting spray over the whole tent , plants and coco ( lights off)

I'm off down he grow shop now for some nutes so if anyone can recommend anything to pick up to fight this while I'm there would be greatfull

What the he'll is this now.. Same plant all others ok just the one that appears eaten has bright yellow on this leaf .. Added canna calmag about 5 hours ago....

Here is a pic of the rest sorry my hps is on will get better pic in the morning when it's lights out

how's the grow going now?

I'm still having a few issues... Lower leaves yellowing / falling off a few could just be because no night down there but also have purple stems on bottom and top and some very slight brown spotting to end he of leaves ... I think it's still a calmag issue...
My tap water is ec 0.2 so I dunno if this is something to do with it I was a bit unsure how to use the calmag

This is around 3 weeks and 2 days into flower

Little bit of heat stress brother.
The one leaf has what looks to be cal mag issues. Other than that looks great!

Wow that's something I have not heard of, another reason to love those nagas.

Don't worry about leaves dying, unless they have some janky shit going on.. I think they look good.
