Ex Canna user here. I’ve been running Canna complete line (pH+,pH-, CannaCure, etc.) for over 4 years now and just switched to Athena last run. I also noticed a change in taste running the same phenos. I feel is mostly due to the Boost and Cannazym which are the two best products from their line. Personally I’ll give Athena another run since it broke my previous yield record, just wish it wouldn’t compromise so much on smoke quality. Also, last time I didn’t run Stack but this time I’m replacing it with an Hydrolized Kelp which is basically the same but a 1/10th of the cost.Very interesting. Can you help us out and tell us what specific Canna nute line and additives you are using and also the 3 others you tried? Might help narrow it down a bit
