Candles burning out before end of ritual.. Implications?

Say I’m doing a 5 day ritual that requires 3 red candles. Day 5 you let them burn all the way out.

At the end of day 3 they had gone down all the way to the bottom and were barely still going.

Should I replace them and keep going? Does that mean anything? I normally don’t use candles during most rituals so I’m not sure if this means anything or if I can just imagine them going for the remaining 2 days and call it good.

Thoughts?

I would leave it to do its thing.

Personally, I’d start over with a new candle.
Do a road opener or cleansing first.
