Flowering time.. depends on how healthy your plants are?

I have a Critical+ that is on 66 days in flower, usually time is 53-56 days it says. It got me thinking on flower times and the health of your plant. We control feeding, temp, lights and humidity and make our plants healthy probably healthier then they would be growing in nature.

Like a human better health means longer life.. is that true with plants?

seen as you can cut off a plants leaves and have them grown back within x amount of time i highly doubt it, plants trees etc are on a different level

Better health can mean that they'll have a longer lifespan, but it doesn't mean the plants will take longer to flower. Since how they're grown affects flowering time, a breeder's estimate on it can really only be compared to the breeder's estimates for other strains they offer.
