Buds are looking quite nice and are bulking ..... pistils are still showing growth ( calyx still not mature ) , IMO I would keep a feed going ( although I’m not to crazy of 2-2-6 ( pk numbers ) ... I thinking an easy 3 weeks . Light stress can often show “ extra “ pistil growth at bud “ tops “ those getting the most light , hence the Fox tailing.
Fox tails often happen from light , heat and genetics ( latent too ). Those will look like fingers , not pretty but smokeable .
So , I say stop flushing continue to feed it since it’s showing buds pushing forward. Those buds will look a lot different in another 2 weeks. Then as you notice more pistils changing and coloring off / recede begin a tapered feed ( 1/2 strength ) to end with just a simple watering at least a few days before deciding to cut. Plant will be cleaner at end and not hyper loaded with excess Nutes.
