New Guy needs help ( Please )

Hi, I’m a New Grower and I’m asking anyone who might know the Answer.
My plants were changed to 12/12 and started to flower 1-2 weeks ago. I have noticed that my pistils ( I think ) are starting to die and and turn brown hair like at there tips. I have done a lot of research and now officially lost. Some say that’s normal some say no? This is my flower with a Magnifier, is this normal or what should I do.

Most likely pollinated.

I'd be more concerned about the mites than a few brown pistils. From the spots on the leaves it looks like a heavy infestation to me.

They tend to brown and shrivel along their whole length when pollinated and those just look like burnt tips or damage from a spray of some kind. Have you sprayed anything on them since they began to flower?

The way those plants are stretched out, they’re probably too far from your light. As for the pistils, mine look like that after they get pollinated. But some kind of damage is possible as well.
