Flushing with organic fertilizers?

CTCan
CTCanstarted grow question 4 years ago
Should I flush when using organic fertilizer? I’ve been adding some bat guano during flower and had super soil to start. I’m probably close to 2 weeks before harvest, maybe a bit more. Should I start to use only water from now on? The girls are showing deficiencies though.

In my opinion about flushing Flushing organic soil -you don’t need to flush organic soil.They are acting like slow release fertilizer for your plants.You will not get any toxicity in organic soil as long as your soil is in proper pH range.By flushing,You only wash away minerals like beneficial bacteria and microorganisms from soil. Flushing inorganic soil or soilless medium -Not like the organic soil,When you flush inorganic soil or soilless medium, You will wash away everything you feed that are still in your medium.So most grower did their flushing when it comes close to harvest.By doing that, plants will only get what is left in their system and start showing deficiency.When harvest, there will be nothing left of any inorganic material and you will get nice smell and taste buds.Another time for flushing inorganic soil or soilless medium is when you see some nutrient lock out followed by toxicity.That is due to improper soil pH and excess use of nutrients.By flushing, you will get rid of what’s excess in your medium and flush until your run off ppm show 0~50ppm and pH around 6.0~6.5.After that you need to feed your plant, the right nutrients types and right concentration in right pH range.Happy Growing... ✌️

Flushing has been shown to be pointless, organic or not. You're not getting rid of anything that's already in the plant, you're just starving it of nutrients. It sounds crazy, I know, and goes against what every grower has believed for the last 50 years, but do some research. The science says "no" to flushing. Hope this helps!

You do not need to, but I would still do it like for one or two weeks, just in case there are any residues from the wind/the rain. Good luck :)
