I watched a Zakk Wylde video once where he demonstrated "lowering the strings" by wearing the guitar and reaching over to the truss rod nut and cranking it a quarter turn TOWARD himself (or up if you like) in order to get the strings lower when he needed to correct for weather while touring and playing various outdoor venues. I know that he was actually removing relief or applying backbow, however you want to look at it, which gave him what he perceived as lowering the strings. I use this example for myself to remember which way to crank the truss rod for a minor adjustment.
But, keep in mind that Zakk was playing a Les Paul which has a single action truss rod while PRS guitars (for decades now) have a dual action truss rod. You still turn the nut the same direction but just keep in mind on a PRS it is the middle of the fingerboard which "goes up and down". Depress the lower E string at the first and last frets and see if the string is touching the frets in the middle or not. If there is a gap above the frets in the middle while you are doing that, you need to add backbow (crank it toward you). If the string is laying against all of the frets, crank the nut away from you to add relief until the neck is perfectly flat. THEN adjust your bridge height if needed or possible.
