As I said, I'm not a user of ferts. But, above you stated a 16 6 30 fertilizer. If that's not a typo, that sounds like a lot of nitrogen for flower.

Light Ian evo 8 -750 watt led light frame not sure if it’s manufactured by Samsung or uses Samsung diodes. As far nutrients, I am using Bergman‘s plant food stage three flower time fertilizer NPK 16 6 30.fertilizer is from I♥️GM website. as far as the height of the light, it is 26 inches above the highest point of my tallest plant and it cannot be raised any higher.

Do you check your runoff ppm and ph? That can help tell you if it is a deficiency or nutrient lockout. Check ppm and ph going in and runoff. They should be somewhat close. If runoff is a lot higher you may have a salt buildup land nutrient lockout and may need to flush your medium and get it back in a good range.
