She looks about ready to me. I would start giving water for the next week or 2. But I may be totally wrong.
I grew Durban poison, one of the best sativas I have ever grown or smoked. Some of the buds had some foxtails. They did not bother me one bit. Some of the tails were huge, like buds just splitting. No one complained and it definitely was not a heat or environment issue. Some people really trip out about the foxtails and I think they are wonderful.
I only had one of my Durban’s pistols change color. It was enough that I could tell it was changing, but faint.
When they cured, they took on more of a red hair appeariance.
