Hi Dinesh! Thank you very much for spending some Q&A time with us here! I'm Waira, and as the Infirmary guy here, I'm keenly interested in your products,...
Deficiencies are hands down the most common issue I see, pH related or not; toxicity much less often, and more difficult to diagnose,...
..I've been touting the virtues of foliar spraying for years because of it's diversity of applications.. the 3 F's if you would-
-- Feed, Fix (defc.'s), and Fight (vermins)... BUT it needs be done right to get best results, and avoid the hazards,.. critical to this has been the need to use wetting agents/water spreaders (to get max. surface area coverage) and along that line, spraying the bottoms of the leaves...
...your products deliver in a way that circumvents these restrictions and requirements
... can to expand on how they are working around the cuticle layer? Tinkering with stomata openings is one thing, but as a "mechanical" barrier of sorts, the waxy layer seems a challenge to get through...
... also, along that line, usually stuff needs to be in aqueous solution to get into the leaf via the stomata,... I understand that there's no need to spray the undersides of the leaves where most stomata are,... I gather in part this is because of the work-around of the cuticle layer penetration... but is there something in there that opens up the stomata as well?
