Picked up a Poseidon X Ambition. For under $700 it’s a great bike and one of the most comfortable bikes I’ve ridden. But still I feel it’s kinda cheap, I don’t trust the wheels and I’m not sure the full carbon fork would handle the weight. I could see upgrading the wheels but not sure what to do about the fork.

I looked up the bike. I don't see a problem with it

I'd tour on it. I tour real light, so I would definitely not be too concered about either the wheels or the fork. I think it would be fine for folks who toured with moderate loads too. If you want a real pack horse to carry really heavy loads maybe you might want something else, but personally I find more joy in keeping the load down and having a nice relatively unladen ride regardless or terrain or trip length.

Looks like a pretty nice bike for the price.

I too looked it up and the fork has 2 mounting holes, is rated to 3.5 lbs per fork leg, so if you stay within that limit, it will be fine as it is designed for this, plus you could put a handlebar roll on also. It has mounts for a rear rack also, and the gearing is reasonably low also.
Wheels are 32 spoke and Im sure are regular old mid quality wheels, but again- if reasonable with weight they probably will be ok, depends on your body weight also.
Riding it for a while and then paying a good wheel mechanic to go over your wheels and properly tension them will go a long way to keeping wheel integrity.

how about you give us an idea of how much stuff you'd put on it, how youd do this and how much you weigh. If you weigh 250 that might be a diff matter.

I’m 185lbs, my last tours were done on a LHT so I carried everything. I’ve been considering leaving more at home and touring with less gear. I figured out quick that most of the things you think you need end up not being used. I was thinking the front fork bags could be used for a couple extra shorts and shirts and put the tent and heavier items on the back.

Using an Old Man Mountain rack that can be attached at the axle, would increase your load carrying ability.

those bikes are a bargain. I think you can find a way to tour on it.

the gearing is about 23-94 gear inches, so I'd compare this to your LHT and figure out if you'd need lower gearing for what you would carry. I personally would want a bit lower, but then I'd also want a double to get a wider range.
Also, the cassette 10 spd of 11-46 or 48 has some pretty big jumps in there percentage wise. Again, up to you to know if that would bug you or not. It would me.
The gearing could work for you if you went rather light, but again, thats up to you to see for you how it is.

what is it?

Polaris OBark

Get a second, steel, fork, and use that when you tour. Front-loading the weight is a good option.

Or get a third-wheel type trailer.

I don't see a single thing you need to change on that bike, except if you plan on touring in very hilly areas, switching out for a smaller chainring.

Solo tour under one month duration, two rear panniers and a saddle or handlebar bag will do. Nothing needed on the forks.

I wouldn't worry about the fork. Koga-Miyata is one of the most respected manufacturers of touring bikes in Europe. Their mid-level touring bikes have either aluminum or carbon forks. No steel. Their trekking bikes (i.e., their heaviest-duty touring bikes) have aluminum forks. No steel.

I looked it up also. It is a gravel bike. It is not designed for touring with racks and panniers. It is designed for bikepacking with mostly frame mounted bags. This is why there are more frame mounts for water bottles and other accessories. You can put racks on it and use it that way. I wouldn't trust that fork for a touring rack and panniers.
