SOIL Untypicall leaf necrosis - pests or sickness?

[Pukapith]

Hello, I have my autos on outdoor. One of them has stains beetween vains, whitch is turning in to necrosis.
I didn't found bugs on it, but there can be absent, but come back.
I've seen them on some plants around - black and yellow aphids. My spot is also high humidity, because it's near to river, so I was wondering about some fungi.
Searched a lot, but haven't found anything like this.
Has anybody seen this symptoms?
Please help

It goes from bottom leaves, so it could be either deficiency, or pests.

Thanks mate
Could it be ants?
I've seen lot of them near my plant.

Edit: Probably those are root aphids.
Is this one of this f**kers?
