Nirvana isn't supposed to be grown with just a single pack or a single fem seed. I always go with 40 seeds per variety, because those folks charging 100+ aren't really providing stability either lmao, be it landrace or s1 there will always be variation, some people prefer indica Dom, some sativa dom. On the topic of Nirvana in particular, they usually have over 4 phenotypes per hybrid, like Ice and Aurora indica and Bubblelicious all have 'sativa' phenotypes that are my favorite versions despite their parentage being afghan, bubblegum, NL, skunk. The stuff they keep selling is the reliable high yield/quality line, so you do have to go looking or get lucky. eventually I know I'll revisit ice and the Bubblelicious, I lost plants due to error many years ago, I could easily sort through 40 each without it costing much other than soil. Some brands you are given a photograph and are expected to find that 1/100 phenotype anyway. Alphakronic, swerve, and a few others who used to frequent here did similar shit. Spent over 1k looking for a legit blackwater plant from Cali connection and wound up with stuff that was worse than the gear I spent nearly 100 on. If the seeds are inexpensive, it's like playing a cheap lottery with very high payoff.
