Autoflower buds getting brown end of week 5. Help!

Hi, I am first time grower. I am finishing 5th week with a Jack 47 XL Auto from Sweet Seeds. I am using only rich soil with perlite and worm castings. 20/4 light schedule with 3 cheap 70w LEDs. Wattering every 2/3 days. 11 litres pot.
Everything has been going great till now. I see in most of the buds that some of the internal micro green leaves (not the white pistils) are turning brown and I dont know if its normal. Its happening in the buds close to the light and also in those farther from it. Besides this, the plant looks healthy to me. Can anybody tell me what could be wrong, if anything?
Thank you very much.

Anyboday can give me a hint? I thought maybe its light burn so I have increase the light distance, but I am not sure...

I'm by no means an expert at all, but they look pretty fine to me, I believe when the leaf tips fold over its due to a slight ph fluctuation in the soil, I could be wrong though.

Thank you very much for your answer. But what I mean is the colour of the green micro leaves inside the bud. I add a new picture where you can see more clear what I mean. I dont know if it is normal that they turn brown as I dont think they are pistils but I may be wrong. I dont know. In any case, thank you.

Yes, I guess it is just insecurities of first time grow. But searching around I rarely saw something like this. With the lack of experience I really dont know what is a sign of problem or what not. Thank you very much for your answer.

They look absolutely fine, let them be, the hardest part of growing Is just leaving them alone, if you try to rectify any little issues(some that aren't even issues) it will probly cause more issues.

I will let them be, thank you very much. Now I feel more calm about this.
