Rooting hormone

Hello everyone...

Does anyone uses rooting hormone like nutrients to boost root grow???
I`m just planning to grow some autoflowers and i had an idea... i could add some rooting hormone to water when watering my plant in first weeks so the roots would grow faster and if the roots would grow faster then the whole plant would grow faster because it could get more nutrients from soil and so on.... what do you think about that??? how much hormone i would need to add to the water???

you can but it may over grow i'm not sure i'd only use it for clones

i'm not sure most rooting hormones are water-soluble. some people on here put clonex solution in their cloning tanks. something like this:

even though that's not marked in the listing as specific to rooting.
