Hey DGC- Trying BioBizz coco coir this run. I’m finding it to be much cleaner than the GH CocoTek PX that I’ve been using, My only concern is after rinsing and buffering the new coco I can’t get the runoff below 7.0 PH. I use bottled organics and have flushed with 1/2 strength nutes and plain water ph’d as low as 4.0 and still the runoff is 7.0-7.2. I’m anxious to transplant my small plants in beer cups but fear the high PH will shock them. What can I do to lower PH ?
Thanks- Lord Blueberry
