Between the "flushing" advice and "NO tricks" statement.....There IS a REAL answer. (excuse me a moment while I finish snickering at the previous answers).
Sulfur. The type it is and the amounts delivered, enhance flavors!
There are "Flavor enhancers" put out by nutrient companies with various claims......The laughable part is those that claim specific flavoring, usually by bright colored labels depicting Grapes, Pineapples, etc, etc. In truth, you can deliver S in several plant usable forms that each have their own taste "profile".
Mag Sulfate = A berry like note.
K (potassium) Sulfate = a Citrusy, rather Lemon note.
These 2 compounds will also help increase trichome production (more trich's, more odor and taste) and actually help fatten up the buds, increasing your yield a bit.
Many of these nutrient maker supplied products. Simply combine like amounts of each and are the exact same formula. No matter what "fruit picture" is on the label...They are stupidly expensive. Avoid these! Then there are the "Terpinator" and Resinator" brands. each claim about the same but, each has it's own concentration and feed charting! ( Resinator has changed it's formula a cpl of times. Most likely a legal issue over another formula, by another company. Resinator also contains unneeded P in it's new formulation.) Terpinator I find as low strength and not as efficient as it could be. One of these is expensive and the other is stupid expensive! These are K sulfate formula's and are the lemon/citrus ones.
Then there is Botanicares SWEET RAW. A simple (and I mean simple) Mg sulfate (Epsom salts) and complex Carb supplement that works pretty darn good! BUT, (Oh, oh) it's $65.00 a gallon or MORE! This is the More Berry/grape one!
I looked at these and laughed.....read the label, do some math, and I came up with a "Sweet Raw" you can make in your own kitchen for less the a $1.00 a GALLON!
I got asked if I could do that for terp and resinator too! I took a look and......
Came up with a formula for a 10% K sulfate and complex carb supplement ( I felt that this was a more effective concentration if you follow the feeding chart I listed), and I also listed a safe feeding chart for it. Instead of the cost being like "Sweet Raw" or higher...You make a gallon for about $4.00 a gallon!
All I can say is that these things work! If you buy organic OMRI sourced ingr. Your organic.
Search here on this site - Home made Sweet Raw, and Home made Terpinator, Resinator and use my screen name as the filter....You will have those formula's and the sources for the ingr.
Good luck!
