Any strains pistils don't turn red?

Are there any strains where the hairs stay white and don't turn red? If so are they usually sativas? I have Ace's pure sativa ethiopian. They're supposed to be done in 14 weeks. I'm at 18 weeks. Trics are 30% red so I fear I've gone to far. Buds are whispy like pure sativas apparently often are. Variety is not supposed to be strong at only 8 - 12%. They aren't very sticky. About 10 days ago I reduced light to 11/13 but still no change.

I've heard of buds where trics don't turn red but haven't heard that of pistils. Is this the same thing?

Uh well no helpers to help but I may have a possible answer. I discovered a light leak. Not positive that is the reason because the earlier harvests were fine.

They should turn red given enough time, some sativa can take up to 24 weeks to finish

Hmm, thanks. Well maybe I'll pick 1/2 so it's not a complete loss because they aren't happy. Then keep doing the rest for 6 more weeks on 10/14 and fixed light leak and and some flush with light nutrients.
