I disagree. I see no fallout whatsoever when they are mixed and I think they are just covering their bases so nobody mixes it up with something else and then blames them for it not working.
Yea could be calcium is quite reactive. On their site tho it says it's a mixture of calcium and plant waxes when diluted to a certain strength the plant can assimilate it better. So I dunno, I just spray it separately
From the site:
Calcium-25 is a unique crop yield-enhancing product, and is composed of only naturally-occurring ingredients: calcium and certain amounts of plant waxes that occur on the leaf surface. The combination, when applied to the leaf surface of growing plants in water solution under the right conditions, is absorbed into the leaf as a carefully balanced mixture that can be recognized by the leaf surface as being all-natural components.
As a result, the mixture is absorbed into the plant and calcium is actually translocated in the plant. This makes Calcium-25 different than any other product! This absorption causes a rapid increase in plant growth at an early stage of plant development. The stimulating effect carries over to a final increase in crop yield."
Calcium normally isn't very translocatable. So if what their saying is true, the whole selling feature that makes it stand out from standard calcium foliars, then maybe it won't be as effective? I follow you on insta I know you're a busy dude thanks for your time, peace:)
