I have a giant sack of the latest version in Canada. It has a version 2 label but we swear its version 3.
I use it in veg on hand water plants...it should last me the rest of my natural life.
I am switching to something else full cycle. Other products remain constistant in formula over time...This ever changing formula...how do we know what we have etc...
I went back to a 3 part for all water systems and everything is growing better with less crap in the res.
I love the value but i want consistency.
I will try a bubble bucket full cycle to see. I have 20 pounds left to use
