Look for any kind of bugs at the underside of the infected leave.. Kinda looks like light burn.. How close are your lights to your tops?
 
Red stems and speckled leaves usually indicate a cal-mag deficiency but your leaves are very dark with white/burned tips which means nute burn. How hot is your mix. For DWC change rez and run with calmag only for a several days.... Good luck!
 
Here's a whole plant

How close r your lights also if you get nutes on your plant when the lights are on that will birn them also but seriously that looks like overfeeding not to much can go wrong in that water unless you just trying different stuff in that water I used 3 part gh (strain dependent) no problems, if you having problems go back and see what you did, did you add or take away

Colours? Every pic looks yellow under yellow light. It'd be easier to see if you had white light. HPS pics are horrible for diagnosing.
 
we request problem photos of plants to be in natural light for obvious reasons that we cant see squat looking at an orange , pink or striped lined overlay.
not exactly fair to us to give it a go.

you should also include all information about your plant and what you do to it no matter how relevant or irrelevant you think that information is.
plant problems are like puzzles , you leave out 50 puzzle pieces well than youre just guessing.
