hey friend,
If you're having a plant foxtail and you're seeing new growth(pistils etc) regularly then you'll want to gauge the readiness based on buds a bit further down from your top most colas showing the foxtail.
Going off this weeks one photo your plant looks very close to ready. If you're seeing the lower trichromes turning milky and some amber then I'd say go ahead and give her a mild flushing and cut down in the next few days.
Happy trimming. ✌️
