I already do most of that but I would like to do it to a couple plants and compare the differences. I know tom hill used calcium25 on his plants as a foliar and he said they were noticably more pest and mold/mildew resistant.

The benefits of Calcium25 might be the Boric acid or the Tria that they totally claim isn't in it.

Yes that's why I'm using the calcium metasolate...

I think I'm going to try Biomin calcium next.

I really like the results from metalosate calcium, but I hate opening the container due to the consistency of it.

The numbers on Biomin look pretty similar to metalosate.

I used it for a short period in my perlite hempys. It jacked up the pH both in the solution and the rootzone. I found it to unpredictable. Maybe the fact that it's a carbonate, I'm not sure. I occasionally use it as a foliar but I've mostly shifted away from it.

I mostly use gypsum in veg and Growmore Calmag in veg through stretch, but as a foliar only.

The Biomin is unpredictable, or the metalosate?

Personally I'm digging the metalosate, it just smells like shit and the powder gets everywhere.. then absorbs all the water from the air whenever it lands on whatever surface, leaving a sticky mess.

Went ahead and got the growmore, I couldn't find anything bigger than a quart last time I looked.

The Biomin. Don't take anything I say as gospel, though. I'm still trying to figure out the big Calcium quandry. Running in hempys makes it challenging for me to get adequate levels of Ca into the plants by the end of stretch. I seem to be playing this yoyo game of not enough/too much.

I don't have any metalosate yet. The GM, from what I can tell, only comes in a quart.

Right now I add maybe 1/2tsp of gypsum to my veg mixes, followed by epsom foliars when I see Mg def signs.

Interesting academic site, mentions humic acid in late flowering might impact THC. Lots of interesting articles.

The stuff is sticky....like spray dried malt extract ( for home brewing)...I portioned some out into a smaller vessel for use. I do like it as a foliar. It really helped me to keep things green during the transition when using not well buffered coir. Going to work with it some more to get a better feel.


The Mr. Fulvic has proven to be a great replacement for the now unavailable SM-90....keeping my roots whiter than ever and it has really shined as addition to my cloning program.....from cuts standing in cups of water to branches just plugged into 1/2 gals of coir...boom! lots of white fuzzy roots.

Their source of humic acid could be unrefined Leonardite or asphaltite for sealing driveways with lots of contaminants for all we know.

I'll stick with refined fulvic acid (no humic), thanks.
