Has anyone tried this fertilizer?

I've never used it. In fact this is the first I've seen the Promix fertilizer.

Seems a little high in phosphorus. I believe in using a more balanced NPK. It also doesn't have any calcium or magnesium so keep that in mind as well. But overall it's likely as good as anything else out there. As long as the plant gets adequate amounts of NPK and micronutrients it doesn't matter what brand you use.

The price seems reasonable. Give it a try and report back with the results. I'd use that before spending a bunch of money on overpriced cannabis specific nutrients.

By looking at the content..

You will have trouble in bloom, as the P is rather high.
The result will have higher CBD and lower THC then the "normal" run of the strain with proper feeding of micro's.
In other words. The Fe is twice the MN, and that's not good for cannabis.... To big a spread.
The Fe and the Mn should be near or equal to each other...... More Fe by 50% is too much.

Yes it is rather high in P, is missing some things, and some are not in the best ratio's. But not much different than people dumping all kinds of stuff on their plants because it says bloom on the label without any understanding of what's in it or how it works with other products being used.

It would probably be great for my Dahlia's, Zinnia's, Geraniums, and other flowers but looks like a Canada only product for now at least. Just goes to show how much money can be made of fertilizer. Everyone is getting into the business.

Has anyone tried this fertilizer? First time seeing it on Amazon.

Your numbers are off and is it organic? You want low numbers and organic to promote microbes. A cheap solution is Miracle Grow Performance Organics at 9-2-7. Just a couple of tbs mixed in with some super soil in 3g pot works nice. Try a real hydroponic supply store and you will find a whole wall dedicated to such products.
