@smokeDK Hi there! Yep this looks like a Phosphorous deficiency. In my opinion you're giving way too much nutrients to your plant. You must have created some nutrients-lockout, and now your plant cannot absorb Phosphorous anymore. As an emergency move, I would flush the soil for 3-4 days with plain pH'd water, then follow an appropriate feeding schedule for BioBizz (https://www.alchimiaweb.com/images/xl/bio-bizz-bio-bloom_240_4_.jpg) and see how it goes. Keep us up-to-date and happy growing! 👊
