Maximize flowering sites and nodes for initial weeks of flowering. More flower sites means bigger harvest and improved overall yields. Also can be used as a PK/blooming/flowering enhancer at later stages of flowering/budding.
Do you typically want to lower your lighting when you switch to 12/12?
I'm about a week into veg, plants look to be about 4-6 inches tall. Most are going into their 4th node. Should I wait longer or is now a good time? Also, should I wait for all plants to be at around the same stage or should I top the ones that are ready first? 
When I water, I run 2 gallons of Ro water through every plant. I let them sit and drain for about an hour then I proceed to water them again, but this time with nutes (1100 ppm/6.4 ph). Let them drain, then they go back into the tent. Is that a waste or not? I have no issue.
