Sure the 3 year old will learn but she'll probably crash and burn
Plants like to be vegged though.. What you're doing is creating more photosynthetic capable tissue that can be used later to direct and harvest a larger amount of energy towards flower production. If you flower right off the bat you're making your baby girl drive a car at age 3 man. Its better to wait until she's mature.
But do what you have to do, it will still work. just not as well
