Not the best pic quality but from what little can be gleaned from it, it looks a little ( or a lot) light burned.

Sorry pic is really poor. Will try for better pic. Thanks for reply. Will adjust lights accordingly. .

Im no expert,but that doesnt look like light burn to me.More like a K def,maybe caused by your ph being off,or too much P which causes K lockout,among other things.

Gotta admit that pic leaves a lot to be desired, next time take pic with HPS off, could also use more info, what nutes are you using, what ph, what ppm's?

light/heat burn, raise the light.

I agree, overdose of something.

i would say nutes burn or the light is to close
