Pics kinda bad due to hps flooding pic with yellow and orange-cant see chlorosis, yellowing, clearly. Which you may not have.
Im seeing the edge of the leaf crinkle and curl along with your fan leaves droopy and limp.
Crinkle and curl looks more magnesium issue. Not deficiency per se but likely VPD, vapor pressure deficit. Check water pH, soil pH or run offf pH.
Droopy leaves could be need for phosphorus, which could be caused by the VPD and or pH.
VPD kinda shuts down water and solutes in the water from moving thru the plant.
Just somethings to look into....
