40+ year old seed (unknown strain)

I expected this girl to flower just as fast as any "modern" strain would. She's taken ~3 weeks of 12/12 just to form budsites and show pistils. Lesson learned. Rusty tips are back, but I suspect they come from light stress. She is a picky little chick. How the tent is filled right now, there's simply no way to sufficiently accomodate her requirements. Let's hope she won't be too bitchy about it...
