Can you use a root stimulant through entire life cycle?

I use half a TBS of Getaway Mountain's Seaweed juice per gallon on my seedlings and 1 TBS per gallon on young plants. Really helps with root growth. {thanks to the Captain for the test jug}

I cut root supplements after bud sites form. I think it's a waste to be using them mid/late flower since the plant is focused on flower production in hopes of pollination vs root expansion for plant growth.
