hey there again, i took a look at your video, and i have some good news : there is no foxtailing happening. Basically there are several types of of flowers as you know , this one is just looking a bit more like that. When you see foxtailing it's much thinner and it grows like a ladder upwards. here you see some dense buds and they will get denser for sure. Good luck growmie, hope this helps ! 🚀
