I switch the lights to 12/12 then 2-3 day's later I switch the nutrients out to flower nutrients and then add the MOAB to kick start them for the first full week of 12/12. In truth I end up changing my nutrients out every week they just drink up that much that fast. It's easer to change them at that time and give fresh nutrients for me anyway.
