You start counting the cycle of life even on a clone when you leave your cloner and start week one nutrients in the vegetative cycle. Sure clones inherit the age of the mother yes but when they first root you need to grow them into plants first. Just having roots and leafs out of a bubbler is not enough. Week one is 400-800 ppm week 2 is 800-1000 week 3 is 1000-1400. Each week you can see the nutrient requirements change as well as the percentage you mix. When you start with a range you don't always go with the highest number in the ppm range.

You don't start counting your plant life cycle on the day you put in in the cloner.
