I would say yes.
As long as you keep getting fresh white pistils popping up and no other weakness sign on the buds or leaves, that would be normal. Eventually, all of them will turn out like this.
I have autos on day 42 with about 1/5th of the pistils brown already, so my guess is you're good.
I cannot see the whole plant in the pictures but from what i see, nothing to worry.
