Gorilla Glue # 4 problems

What size containers do you have it in, and how often do you feed (with every watering, or nah?). When you say the par is in the right range, what does that really mean, what are your numbers? I think you might be getting some light stress, but there's also some root issue. Too much nutes, or not enough? You've been vegging for 12-weeks? It must be a big plant.
I believe you may be totaly correct ! Now plants are all dying ! Ph was to low, and husband had lights turned to high and was cooking the heck outta them . I’m sure it’s to late to save them.
