Premature Pistil Colour Change?

[NotAFridge]

Hey guys,
I'm doing my first grow using FemaleSeeds White Widow x Big Bud auto
Growing in soil using the full range of Canna Terra soil and nutrients.
I'm nearing the end of week 7 from germination and my buds stiĺl look very premature, but some of the pistils are starting to turn brown already. Is this normal?

The majority of your pistils are still white so nothing to worry about. Looks good

Thanks! Was a little bit worried that my lights aren't powerful enough...

Worry naught, all is good.
