The pistils look like they drying out. It's either too hot. Light too close or not enough RH. Trust me Daddy had the same issue. And buds didn't preform bc of it. You shouldn't have deficiencies if you are organic bro so rule that 1 straight off and quit flushing her. You are only washing away the microbial herd you worked weeks to achieve. Hope this helps you as I had to figure out on my own. I can almost guarantee its your lights too close and too intense at this stage of her life. Build your herd again and reduce the intensity or increase distance. 5-10000 lux for seedlings, 10-20 for veg and 20-30000 for flower increasing throughout her life until the last two weeks of flower at around 30000 lux. Hope this helps you
