Help idk what’s wrong 3 weeks into flowering

Help idk what’s wrong 3 weeks into flowering and the leaves are brownies and cruling. I’ve included various pictures please any information or recommendations would be great.!!!!

I can't say 100%, but I would put $ on it that you're over fertilizing. Looks like classic nute burn. Some deficiencies cause that necrosis on the sides of the leaves too, but those burnt tips are most always nutrient burn in my experience. It's not that bad though! Flush with 1/4 strength ferts pH'd at 6.3-6.5 and just let them chill for a few days. They look pretty young, don't give them full strength feedings yet. And don't stress too much, I've had a lot worse, they'll pull through.

So just 1/4 of the nutes to her?

Flush the soil with the 1/4 strength nutrients.

So this is her ever since the flush idk what’s wrong with her.
