It kind of seemed to me like the coco needed to be precharged and buffered or something with Cal mag. I still rinse my coco and sift it with Ro, add calmag and base nutes to bring the ppm around 500. I am using canna coco bricks now but I still did this with the bagged stuff
after charging the coco I then add ph up/down(typically up) until it is 6.0. I then let it sit in that water until the ph stabilizes which I’m patient for and will sometimes change. After everything’s ready I drain the water and use it
Coco substrate can act as a buffer, storing water and nutrients for the plant. Buffering can work in several ways. There are water buffers, pH buffers, nutrient buffers and the coco buffer. What are the differences?

I am new to coco so I’ve been doing this all with no problems, but if it’s not needed I would love to not have to do all that shit!!! I hate going through that process
