I have just used this, and am finally able to contribute to this thread. Methods are as follows:

Used at the rate of 1mL/gal, in pH'd molasses water, on soil-plants. Lights were raised 9" as well. I stopped feeding nutrients to soil 1 week prior. I should also note that my plants had NO fan leaves at the time of application due to prior pH problems; plants were strictly composed of healthy flowers and stalk/stem. Flushed as part of the pre-harvest flush 72 hours post-application

The results were undoubtedly excellent. Flowers have thickened quite a bit compared to controls (grown in same environment, nutrient sched. etc...). Trichomes became greater in number and size. The increase in density appears to be due to an increase in resin production, as opposed to only water mass. My yield was enhanced by a rate of 1.5X, compared to flowers of the same size of controls. Plants were stressed minimally throughout this entire process due to recovery from pH issues.
