Take better pics
Switch the hps out for the mh for pics and maybe we can help you.
But so far looks like nute burn.
What was the ppm?

you should flush then feed 1\4 strength nutes after soil dries out

I'm also doing some vast and fast autos. Recently noticed a huge amount of fan leaves yellowing and dying off. I was very strict on 1/2 nutrient feedings but the tips went yellow almost indicating a burn. I wasn't sure what to do so I did a high nitrogen foliar spray, a heavy dose of foxfarm nutes and another feeding of biobizz shortly after. Since doing so the plants haven't changed much at all. I'm not convinced they need so little through their life.
The above picture looks like a nute burn for sure.

Weird to fix a nute burn with more nutes

They are correct. Leach plants and use 1/4 or 1/2 strength nutes until your plants come thru it. Dont add more nutes to the leaf. More nitrogen is going to further exacerbate the problem. For the most part these plants can live through almost anything except too much care. (Cant tell if this is soil or hydro) but looks like the plant is too small for the amount of nutrients you gave it... without seeing any data.
If you recently added silica it may have made the nutrients more mobile. Stick to 0.5ml/gal silica for most applications, mix it FIRST and thoroughly so it doesnt bind up everything else at the bottom of the bucket.
Watch pH.

I'm growing in biobizz light mix,Also biobizz nutes grow,bloom,top max I've only fed them once with half dose starting when they started to flower,I use tap water but leave to stand in buckets for 48 hrs to leach before watering but I do agree it looks like note burn just don't understand why my plants are now 4 1/2 weeks old here is a better picture

The reason I added more was because the whole plants started looking deficient. Leaves were yellowing rapidly.
Its been 48 hours since the feeding with very little change.

NEVER START AT 1/2 stength i started all mine at 1/8 then 1/4 now im at 1/3 next week will be 1/2
