What happen

Not enough fresh nutrients at the root tips.

Check your run of ph (should not exceed 6,5) and adjust it if needed. When you've adjusted pH and you've created the right environment for her roots, give her normal npk because she def needs N (yellowing) and K(purple color on leaves ). Always check pH and ec of your irrigation water

You getting enough runoff in the medium when feeding them all that AN product line? When I have seen this on my plants it normally because my PH and watering habits where bad causing other issues, but I'm growing in soil with amendments and its slightly different situation. Check out this leaf chart and see if anything is popping out to you. It might be a combination of things. Like N and Mg and S with to much P. https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg Some of the plants in the background look like they want some more N, yellow on lower leaves progressing up to the newer growth. Good Luck!

Hi Bro dein Mädel ist total überfüttert die Blätter haben krallen und sind blass was auf eine Stickstoffsperre hinweist. Du gibst ihr zwar alles aber sie kann es nicht aufnehmen. Am besten nur Wasser geben mit genügend Abfluss die nächsten 2-3 mal. Viel Glück und Erfolg 👍

I don’t know my arse from a humidifier, but since it looks like it’s just the top leaves, it may be that your light is too close to the top of the plant. Looks like light stress
