Bro, you're not the only one dealing with this today, you're already the third one in an hour with the same nitrogen overdose problem!!!! 👆 You've had issues for a while now, you're not the only one who reached out just when it got so BAD!
Nitrogen overdose, it's already at the stage of saturation, the tissues are trying to die off, I see that the leaves at the bottom are glossy and very green! This problem has been with you for a long time, my friend!
At first, your plant was very green and beautiful, but everything went sideways with flowering! The leaf stems are red - phosphorus deficiency, it's blocked by nitrogen overdose! That's a disaster! It's one thing on top of another! You need a flush technique and definitely add fresh soil on top if the flush is strong! 👆 Check your runoff ppm when watering!
Reduce the Gro supplement by 4 times! Increase the Bloom supplement by 3 times! Ratio 1:4 Gro:Bloom! Give 50% of the recommended fertilizer dose from the manufacturer!!! ✊😇
I don't know what you're growing in.... if it's just coco, then no need for a flush! Just change the solution, set the pH to 5.8 like for hydroponics during flowering! 👌
And water it with the runoff, measure the ppm of the solution you're pouring and the drainage! Compare, you'll find out if it's eating or choking... definitely needs acidic water, it likes to drink it a bit sour ✊😇
Good luck, my friend! I hope you save her... but she's a tough one 👆
