Flush Flower Feed

What is the best order or process when making the transition to flower? Before I make the change to 12/12 I want to flush, is it better to flush a few days before, the day of changing lights, etc. how should I schedule feedings after that. Can I flush,transition the lights and feed right on top of each other?

why you wanna flush? i usually feed veg nutes for a bit after flipping to flower.

flush whats this thing use speak of ?? i never flush lol and im in soil sorry i lie i flush the last 10 days dont ask why ten just been doing it that way for about 2 years killer dope real no nute sparkle

I only flush the last week before harvest. Switch up to flowering nutes and flip the lights!! I also give them 48 hrs of total darkness during that flush week. Usually day 4 and 5 of flush.

Thank you for the input. I was thinking about flushing before flower because I used a product called "Ultimate-Wash" to get rid of some mites. It's mostly water but I thought a flush might insure a cleaner final product. Sorry I left that part out.

I saw @Silky said that he continues veg nutes for a few days after changing the lights. Is that optimal? Have you experimented doing it the other way, starting the bloom nutes while you're still on the longer light cycle? just curious

BTW, two applications and the mites were gone. It worked really well.
