see all the stuff you're putting in there, bluesbreeder ? many of them have nitrogen in there. That's why i dont think it's necessarily the N deficiency, but much more likely the N lock-out that ends up almost looking like N deficiency. How can you tell it's not a deficiency though? well if you look carefully some leaves are a very dark green. that means too much N. Simple as that. Hope this helps ! 🚀
