I know this is a topic of debate throughout the community. But I’m being realistic here. Using a dry organic amendment takes some really good timing on last feeding and a perfect eating plant to take up all the nutrients leading up to harvest. Sometimes it doesn’t go as planned and you get to the end of a grow and there are too much nutes left in the soil. Do you guys still believe in flushing organic nutrients in the end or do you let it go because it’s organic?
This is all opinion.
I personally don’t want to flush but I have found myself in this situation a few times and I still do. I flush until the runoff is clear. It seems to help with fall colors for me.
I always flush at the end before harvest. Even if you don’t have dry nutes in the soil and you’re feeding with liquid nutrients, I recommend flushing.
After many grows the taste was better, the smell was stronger. Personal experience
I have used liquid nutes exclusively up until about my 3rd plant this year. The liquid nutes are much easier to time to let the plant naturally do its thing at the end. But with the last 3 this year I have used an organic dry amendment. The first one had way too much left in the soil in the end and had to flush. This Cannatonic I am growing out now started fading when I still had a month left until harvest so I had to give her some more. She’s still fading now on the lower leaves but the tops are all deep green and healthy. It has been so hit or miss. I know for next time but growing out a new strain is tough to time it. That’s where flushing is so important.
As far as taste. Yeah 100% better when there isn’t a ton of nitrogen left in the buds. They taste like grass if you don’t get the nutrients right. Even organic growing.
I’ve wondered this myself & tried both methods a couple of times. I do not personally notice a difference in soil but I have never grown in hydro or used liquid nutes. I often don’t flush anymore but I always wonder, lol.
My opinion:
I don’t believe you can truly flush organic nutrients out of the soil in the same way you can with liquid nutrients. Soil thrives because of the microbial life and since the amendments are slowly broken down over a period of time they are essentially built into the soil making them more difficult to “flush”. Whereas liquid nutrients need to be consistently added in a hydro set up to keep the plant alive making them easier to flush, they arent utilizing any microbes for uptake because these products are designed to be readily available for the plants as is.
On the other hand, continuously watering to run off in a soil set up does slowly remove nutrients over a period of time. However, I am not convinced that a flush near the end of flowering will be a difference-maker in an organic soil set.
