It's not a foilar technically but regalia will kick it up a notch. I use yucca surfactant. I wouldn't worry about silica on combustion. Whats in the products amorphous not crystalline (DE has a small % depending on processing). I more worry about horticultureal oils.I foliar feed occasionally. I know it helps plant growth, but i am not sold on silica being 100% safe for combustion and inhalation. I am willing to accept the lower yeild without it.
The HoneySundae I have does not like being sprayed at all (at least in flower) not even water.
Something I noticed. I have to foliar spray because of a thrippy situation...I think it leads to tremendously better growth in veg.
I am expanding my foliar applications this year, I have used WCaP at transition and a product called super K fulvate but not so much in veg, really a point at which I am not taking advantage of the plants capability. In the past it was because my environmental controlls were lacking. Looking to add epsom and ???...
Im just hoping its the thrips and not the foliar that are causing your explosive growth.
