What's the problem with my plant?

I suggest googling "cannabis leaves canoeing" and see if you find what's causing that. PH or heat issue may show that symptom.

Did some reading on it and heat was mentioned, I don't think this is the issue as the room runs 84degrees Max with the lights on an runs 74 at night. Someone mentions circulating fans may be too strong causing too much transpiration and to slow them down. Even though they are pretty far from the fans I'm gonna try to slow them down an see how that goes.

Never sprayed with anything directly maybe got water on them from the water wand but that wouldn't be very much water at all and wouldn't be over the entire plant either
That's pretty warm. And, radiant heat at the leaves could increase that at the leaves.
Maybe rotate that strain to a different location, see if the fan affects another strain similarly. And, raise the light at the other location (for half of them) and see if they improve? You could cover a few bases that way.

I do have my fans off for the lights because i was battling room temps i do that the lights 30+" away from these plants. Canopy read 90 degrees directly under the light on top of the canopy with a laser temp gauge.

I did move them yesterday to go between lights but haven't seen any improvement only been 18 hours though.
In post #5 your first pic blow it up and look at the top right hand corner, looks a lot like powdery mildew.
Someone mentioned pH. Obviously you're not a new grower on a budget (your growing big). I suggest buying a Control Wizard Accurate 8 soil probe. Costs about $70 on Amazon. It's fairly accurate for a soil probe. You have to follow a procedure to use it (scour the probe surface before using. Leave in soil 10 minutes before reading. When the scouring pad wears out, use #0000 steel wool.). That might come in handy now if you don't have a way to check the soil ph. (You can check it when wet, dry, halfway there, etc.).
I would seperate that strain and try a few things on different containers. I'd be tempted to flush one (100% runoff) to see if that makes a difference. (Edit: if it's not PM.).

That's possible i thought they had pm but i was also finishing some drywall so i though maybe it was dust. It didn't seem to get worse. Do you think i should treat for pm to be safe? I did get high humidity when my temps were running to low. Any suggestions on what to use for pm?

This is a new room to me, I just built it. Only doing 1 run of soil before switching to rdwc. This is a trial run to make sure I can keep the environment in check. Learned a lot about it with this run but I don't want to slack on this run either.
Yeah I would treat them asap, theres quite a few places it can be seen in that pic. As far as treating it, I only had it once and it was a few years back. The stuff I used was called actinovate I think. I'm sure there are plenty of ways to treat it, look around the forum and see what will work best for you.
