Hey Guys,

I use the full Canna COCO lineup in RO water and decided to swap out rhizotonic for a small bottle of GH RapidStart.

My PH after mixing everything w/ rhizo is usually right on the money at 5.8 (ill often ph it up to 5.9-6.0). When I mixed with RapidStart instead of rhizo, my ph TANKED to 4.2-4.3. I have to use a ton of ph UP to get it back to 5.8-6.0. I have to use so much in fact it raises my ec .1-.2.

Has anyone else noticed this?

I also recommend using citric acid and sodium bicarbonate to adjust ph. Doesn't affect microbes
