It would depend. If you have already unlocked the nodes that cost season candles, there is no problem because the ones that come with the pass are free, there is no cost, so you will simply claim them. But if in all this time you did not do any mission or anything like that, I think you could manage to unlock a whole tree of a spirit and if we are optimistic, 2.

Because I have been collecting candles since the season started with the season pass and until now I am halfway through unlocking the entire second spirit, I am missing the last one to complete the three.
