1st Grow Auto Zkittlez

Hi! The pistils can turn brown early for many reasons. Yours looks like it's heat related but cant say for sure. Other reasons can be due to pollination, touching or spraying water etc.. Hope this helps

Hey! This plant is definitely stressed. You can notice how thin and few leaves she has. Also what you mentioned is a key indicator that she's stressing hard, her leaves went from 5 to 3 and they're very prolonged. As for GYOweed's comment, that's not true there are great auto flowers out there but you have to check the background genetics that way you'll see how strong her genetics are and that way know what kind of training you can do. I personally prefer feminized regular but I've had auto flowers give me 60-80 grams per plant. Recently harvest to little autos from my balcony and they look gorgeous. It is true that they are picky and need special attention because they can stress easily, that depends on genetics, training, the environment, etc... To be honest it's hard for an Autoflowering to bounce back in flower, I always grow till the end no matter what and that way I can learn from my mistakes. Any questions just @ me or DM. Hope this helped. Good luck and Happy growing.

Sorry my friend but what you are looking at is a male pollen sac forming. Hopefully I answered your question and remember Happy Growing and Free your mind one puff at a time.
