Transition to flower flush- How Long?

I have just turned lights back on after 23 hours of darkness and have changed nutes out for RO water to flush.

How long is a good pre-flower flush?

Should I use the GH Flora Kleen?

ANy help would be great.

Thanks

Thank you!

Is it acceptable to add nutes while lights are out?

I have never turned the lights out in transitioning from veg to flower. All at the same time I reset the timers to 12/12, flush with 1/2 oz/gal of Clearex for 1 hr then drain then replinish with full strength flowering nutes. But then, I also just use pH'd and treated tap water from start to finish. I do everything with the lights on. I cant imagine working in the dark with the lights out. Good luck.

Thanks man, I got radar like a bat when I'm high, so I don't need lights.

Okay then. Good luck with that.

I'm fukin with ya, I don't have bat radar, I have a reservoir <---finally spelled it correct on my first try) that located outside of the box my furls are in, so I can do changes and whatnot at anytime. I also keep a fish tank heater in the remote tank which holds half of the nutes.

Remote tank + root tank = 13 gallons total capacity.
I use 2.5 gallons per plant x 4 plants = 10 gallons)

Question about the Lucas Formula and the addition of GH additives. I have Liquid KoolBloom

Should I use my additives?
