NFT use more of a ebb & flow type of feeding schedule. You don't have a lot of room for roots to hang like most drip systems. NFT only having a few inches before the roots bottom out means they will be sitting in running water 24/7 and not have much of a chance to breath. Roots sitting in water run a big chance of rotting, or holding pockets of imbalanced nutrients in your tray.

Play with different feeding schedules, like 15-on 15-off or 30-on 15-off or 15-on 30-off record how they do with a few day's test. In about 10 day's you will know how that strain does with feeding.

Different strains react differently to different feeding schedules so trial and error on your part is required.

Also track the Ph with each schedule too.
