Hey, buddy! 👋
Nitrogen overdose, already at the stage of saturation, the tissues are trying to die off, I see that the leaves at the bottom are shiny! This problem has been with you for a while, my friend!
At first, your plant was very green and beautiful, but everything went sideways with the flowering! The leaf stems are red - a phosphorus deficiency, it's blocked by nitrogen overdose! This is 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 addition by 4 times! Increase the Bloom addition by 3 times! The ratio should be 1:4 Gro:Bloom! Let's do 50% of the recommended fertilizer doses from the manufacturer!!! ✊😇
Good luck, buddy! I hope you save it... but it's tough 👆
