You're confusing the problem by using too many "rocket fuels". You only need a good 2 or 3 part hydro nutrient to grow perfectly healthy plants. Try simplifying your grow next time. As for right now, you could change out your res with fresh nutes and no additives and give that a try. You won't see any improvement in the damaged leaves, but it should stop the problem from progressing.
