Yes, it really will make a difference. I'm in a legal state and I work in the industry. I get to see hundreds of test results along with samples. We are particular up here and everyone wants to know how it shit was grown. (Pnw is spoiled) [emoji38]
There are people up here changing cannabinoid contents based of when they feed the nutrients. I'm talking a big difference, multiple percentage points not just slightly.
As far terpenes go, you can definitely bet that outside influences will change or alter a terpene profile. Bottle feeding will do it, too much heat, too high of ph, etc. Many factors play a role in terp production. That doesn't even include a proper dry and cure which will most definitely effect the overall outcome of the terpene content.
I have noticed that a "true organically grown" plant will have a better overall effect. Force fed plants lack the kick.
Unfortunately you have already discovered it, it will be the same with the autos, that shit lingers around, even after a solid flush. It seems to be the bone meal that imparts the flavor, which is apart of every feed from what I understand.
One bottle is too many. [emoji106] It is soooooo much easier to mix it all in the soil and just give the ladies water. No mixing whatsoever, that's already been done months ago!
After work, I'll be posting up Runty the double grape beast.
