Curling leafs

A few of my plants the leaves are curling, any ideas what could be going on?

The room conditions are:
  1. temperature 81 to 83°
  2. relative humidity 60%
  3. for nutes FoxFarm
  4. spraying CO2, once an hour.
  5. watering/ feeding every third day.
  6. pH level 6.0

I'm not sure what's going on, but it's not all the plants. out of the 9 three have curling.

Are they near to an oscillating fan or AC duct etc?

Looks like you're getting leaf margin curl which is usually attributed to a lower RH at that leaf surface so it rolls to reduce moisture loss.

Get an RH gauge at the effected areas and test RH.

The room is a 4 x 8 x 7 I have a 16 inch fan hanging in the top corner, and a small six-inch at the bottom blowing on the plants. I have since pointed the six-inch fan up and away from the plants, the other fan moves the plants very little.

humidity runs between 55 and 60 I have a control unit, and it set to 60 percent with a 5% dead band, my high temp is 83°, as I mentioned it's not all the plants, I have nine in there now and it's only three of them.

When I have had this exact problem as pictured, I back off a little on the fan and give it a little more distance. Too much causes a windburn that looks just like this.

You are cranking co2 and its probably not hot enough to do so, therefor wilting. Told ya this before and recommended reading about co2 and temps
