It was a mountain river, started fishing at about 7:30am and fished until noon. Tried numerous dries like stimulators and H&L’s, and also tried a handle full of different nymphs. Didn’t catch a thing. Didn’t see any rises. This is a river I’ve been to previously and done well with lots of beautiful holding water, and I’m pretty sure doesn’t see a lot of angling pressure. Would the current water conditions be the reason I got skunked or did I just get served humble soup regarding my fly fishing skills?

The good news is changing water conditions do make fishing a little harder. The bad news is you still had a starter serving of humble soup. If you can blind catch stimmies and still catch fish, then you are accustomed to fly fishing on easy-mode. I am not judging---we all love blind-casting dries, but outside these conditions, we need to use our more technical skills to catch fish.
1.5-2' of visibility is definitely enough for trout to feed. 50F is cool, even for cutties. Brown trout will stay pretty low in the water column. The cooler temperatures mean slower metabolism and less overall energy. Fish will move for 2 things: an easy meal or a big ticket item.
In this case, with no obvious surface activity, deep nymphing is probably your best choice. The nymphs to choose are often not that relevant, but size is usually important. A stonefly and a small (sz16 or smaller) pairing. Personally, i would prospect with a smaller streamer through obvious tailouts and pools to find active fish. Once an active fish is located, then switch to more targetted techniques, like nymphing and/or dry/dropper.
Jensens recently made a video about it (I honestly did the prospecting before the video was released):
