Please Help Plants Dying

[Tritran85]

Please help, just recently switched to flowering mode and I switch from a 600w mh to a hps. Now a lot of my plants are wilting and dying. Everything is the same with nutrient and watering. While in verge stage it was thriving. Please help i spent so much time taking care of her, I can’t let her die like this

Also when I touch the dying leaves, it feels really crispy, so I turned down my ballast to 50%. I’m so sad

Looks like light burn. When you switched from MH to HPS did you raise the light up? HPS puts out a more intense light. The plants should be allowed to acclimate to the new light source. When I swap mine, I raise the light about 18” from where I had it and gradually lower it back down over the next few days.
