Pistil hair brown way before flowering

Hello everyone I have a weird question this is my second try (my first was about 17 years ago ) anyway I had this seed sitting about 3-4 years so I have no idea what strain it is but I know was good enough for me to keep it. She is in her 3rd week of flowering she is beautiful now she has had shown me her sex way before her flowering period now tho those pistil hair are brown, they are at the bottom half of the main cola. The rest is new white hair brances are doing fine also growing me some little tiny buds. Should I be worried about the brown pistil hair? Anyone knows what it means? I dont want to do same mistakes I have 3 clones of her . Some pictures of her also attached any tips much appreciated. Let me know what you think.

I just went thru similar issues with pistils turning brown early in flower, it was due to a lack of nitrogen fertilizer which I decreased too soon. A nitrogen deficiency causes premature flowering, reduced yield and potency.

It also looks like you may need a stronger light.

Wow didnt know, thank you for your reply I sure will fix this on my clones (even that I water them with nutrients now) yeah i dont have very strong lights my main one is the one attached. Unfortunatelly I have her in my little closet if I get a stronger light I think I will have an issue with humidity. Space is limited for now but I will invest eventually for a stronger light and a fan.

Yeah just not enough light. Plant looks overall pretty healthy though. I don't see any brown pistils in any of the pictures you posted.

Premature browning of the pistils can be caused by physical damage (touching, etc). Also if the plant has collected male pollen and begins the seed making process then the pistils will turn brown prematurely.

Yeah the brown ones are at the bottom of the main cola I have attached a photo. The ones coming out now and the top of the main cola are white and beautiful. I havent been touching her at all I respect her personal space (except now to take photos) and I had a male in there but he didnt made it far he became tea . She has no yellow leaves neither burn spots. Is there a possibility she is an autoflowering one based on her little brown hair?
