Just to harp on genetics a little more: I think you are overestimating their role in flavor and taste, especially considering we're BURNING this stuff, not eating it. Really the biggest factor for a smooth smoke is your cure (and your cure will be reliant on your flush.. and your flush will be reliant on how high your nutes were and how well you flushed em- hydro wins over soil here by a big factor). Taste is a bit more complicated..
Can you get some bad genetics? Yeah, but nowadays you'd almost have to TRY and get bad genetics. (You got me if someone grows oaxaca/commercial bag seed- but lets assume most people at least buy some good seed or get a good clone mom).
So starting with some decent genetics: your grow paramenters will be FAR more important than your genetics in determining flavor and taste.
When we (
www.HydroponicSolutions.co) started messing with modifying manganese levels to create a flavor enhancer it was a nightmare: the environmental factors were playing far more of a role in flavor than the nutrients, UNTIL we got the room parameters near optimum (thanks growtronix!). (We're still not sure if the manganese is tying into flavor via its chlophyll or E pathway functions..)
[As you probably know, too much humidity or heat = 3 fanleaf nightmares in most Sativa/indica mixes, which will ROB your crops flavor. If your room parameters are off then your transpiration levels are almost certainly the biggest factor affecting flavor].

Bud candy for flavor? k20 and potassium sulfate makes up most of their formula. I'm calling BS that those two salts are responsible for flavor improvement. If you read the fine print on their labels they throw in some micro and amino mix. Betcha manganese is in the micro, and the aminos are just more BS.
They just sold you $1 worth of ingredients hidden in $8 dollars of ingredients wrapped around their mnfg and dist. costs= $60 gallon..
[They could definitely improve their practices. ESPECIALLY by being honest about it all. I've spoken to the AN guys and what a crock. I talk to them from a hard science and botany background and they communicate back in what amounts to 'voodoo science'].
As long as this BS remains progress is going to be slow..
What did we come up with as a flavor enhancer? Nothing. We tried several micro mixes; the results: all subjective. But what did we expect: consensus on flavor? Gustibus non est disputatdem - there's no disputing taste. Different tastes: definitely. Biggest lesson learned: DONT overdo manganese levels. The first hydro mixers had it near spot on: thx Sachs and Knop (18th century hydro dudes, so cooool).
