Day 27 flowering

White hairs turning and some burning. I'm on day 27. It looks like nute burn maybe. Sorry about the crappy photos.

I don't see nute burn. They don't stay white forever. Have you sprayed anything?

Have not sprayed anything. It's day 29 now. The buds with the redding hairs seem to have stopped growing. Maybe it's an in pie tween stage before a growth spurt.
