Flushing Cannabis Plants – Basic & Advanced Tips

Today on Lex’s World I discuss flushing (leaching) Cannabis plants before harvest and give you both the basic and advanced tips. All links are in the description.


  1. You said flushing before your "pre-harvest" flush can affect yield, but isn't it common among and also a good thing to flush when you first flip into flower? I'm trying to determine if I should flush when I flip.

  2. Thanks I needed this video for the flushing solution cuz im late flushing and thought it was gonna be all bad but thanks nobody else is even talking about the possible flushing solutions if you messed up and are late flushing. Thanks again

  3. Okay so basically can I flush my plants with RO PH water? And how much? Gallons? And what PH!?? And d I water it everyday for 14 days?!?

    Oh yea and do I have to PH? Because isn’t that just putting chemicals to flush chemicals? Someone help! Please!

  4. I've watched a lot of grow videos, lots of good tips and growers, but Lex's World is one of the best! Thanks for excellent information on all phases of cannabis!!

  5. Hey guys . I'm a new grower on week 8 of flower in coco … I've been flushing 9 days now and leaves are still green as can be ( guessing I severely overfed ) . Is this going to effect taste and smoothness … and is there anything else I can do to get those nutes out of leaves ???

    When flushing in soil, if you use and add microbes, then during flushing and even late flower I start adding cane molasses. Here's why!!

    Most people think adding suger makes your plants more sugary. Not the case, plants feed there self made sugars to the microbes, in return the microbes breakdown minerals aka nutrients and also give off other beneficial compounds in the process.

    However during late flower plants become stingy with their sugars and starve the microbes. So they end up going dormant and or dieing off. Therefore no longer doing their job. Adding suger keeps them productive longer!
