Are those leaf symptoms showing up deeper in the canopy? OG leaves can behave like that (fall apart, curl up, get crispy) if there's too much air movement or not enough humidity and you're feeding heavy (over 800 ppm of nutes on a regular basis)
I wouldn't say it's a bug issue or you would be finding more bugs on your leaves and it would have spread, you did post a picture of a root aphid but those aren't going to show very obvious signs of their presence; mostly just strange mg-esque deficiencies and a reduced yield.
edit to add - one bug you could be dealing with is russet mites, check the stems of the affected plants, if there is golden powder on the stems above the damaged leaves and buds you're in for a whole other battle all together
