IVe been using AN from my very first grow. Only gotten better at understanding the products individually with each grow. That’s why I haven’t changed yet. Athena seems to produce some outstanding looking bud, but super expensive. I was thinking of giving the AN connusair a bash, but still expensive if it doesn’t end up proving any better than their coco bloom base. The flornova I will try out at some point for sure.
With AN sensi, it does keep the ph in check. Most of their additives have salts to keep the ph buffer. You can change the ph yourself, and it will remain that way for over 24hr for sure as I tested this myself. But I read that changing the ph yourself interferes with their ph buffering salts in the medium and can fuck with ph. With my tap water, sensi brings my ph between 5.8-6.2
