To Flush Or Not To Flush

[Florushingflowers]

I'm approaching my final weeks and curious whether to flush or not to flush. I am using the Bio Canna range with Canna Bio Terra Plus 'soil'. This is an organic grow and assume there should be no reason to flush during the final weeks but I am confused as to why the Canna feeding schedule shows no nutrients to be added during its final couple of weeks ?

You should not have to flush this grow, if by flushing you mean the traditional definition of moving 3x the container size in water through the soil so as to flush out salts, leftover nutes and debris. This nutrient line is using the new amino acid chelation technology and therefore no salts are there to build up in the soil. It is not exactly an organic grow using microbes to feed your plants, but for our purposes here that definition will suffice. You do not need to flush.

So why do they not add nutrients the last 2 weeks? This is an old holdover practice from the 70's when it was believed that there was a need to flush all the nutrients out of the plants at the end, one so that the nutrients didn't end up in our final product and two so that the plants would put their all into finishing out at the end. This practice has been mostly debunked, thanks to the true organic people growing in mineralize living soil, where the nutrients are full on 24/7 all through the grow and right up to the end. We now know that to get the best buds possible, it is necessary to feed right up to the end. Bro science however still clings to the old ways... and apparently so does the Canna company.

Very informative! thankyou Emilya for clearing things up, there will be no flushing involved in this grow

That isn't their instruction. Press calculate on the link to get the timings. Basically it continues up through harvest.

I use the other Canna medium. It's similar.

What about flushing in coco? Emily you yelled at me for the thought of starving my plants. Lol

Standing ovation!

As well she should have.

There is "flushing" when you flush everything out and just use straight water from that point on. As Emilya said, it's poppycock.

There is also "flushing" to rinse the salt build up out of the medium, and then go right back to feeding.

The second one is fine, as you're really just rinsing and then going back on schedule. You obviously won't be doing that with a living soil, and only when using nutrient products. Even with the new amino chelated stuff, it may still be a good idea to give a nice rinse now and then to keep minerals not being used at the time from building up to excess in the medium. Either way, rinse thoroughly and let it finish dripping. Then immediately give the scheduled feeding.
