Growing for terpenes?

I have a question of my own pertinent to this thread.
I was gonna wait for the next run but heyho lol

I've never intentionally gone for terps, its always been things like giberellic acid through veg to up the THC which i assume negatively impacts terps.
Can anyone clarify that for me please

That pdf is a really interesting read, it seems that bisabolol and myrcene are inversely correlated, which is why it is so hard to find strains high in both, this is exactly the info I was looking for when I started this thread can't express my appreciation!

That thread you linked, it doesnt really contain what i know about GA³.
Should i post a reply to it so people can find the info in the future.

I dunno what to do but those guys had all the wrong reasons to use it and sounds like their doses were miles off lol

Thanks for your persistence @SSR, much appreciated!!

Cant speak to Gi. acid but if you are growing for terpenes, which is a truly worthy cause, I am happy to share some tricks.

I want to have a try at growing for terpenes in the future. You know how it is, you get focused on yield and potency lol.

I want to share the things i know as chances show themselves, shared knowledge empowers people in ways other things can't come close to.

Thank you kindly for the offer and when the next rounds coming close I'm sure you'll get fed up with me and my questions :bigjoint:
Edited to add: you guys are more than welcome, its not me that deserves the thanks. You guys had obviously been doing research i just found you a couple of links

I've just read the PDF, thanks i missed that in the thread. It looks like it may affect the terps negatively which is a bummer but im going to say the PDF is wrong when it states that THC content was lowered. Now i can't accurately measure THC content like them but i know when my girls are more potent as do others lol.

The pdf sums up what I know quite well and in a way more sciency way than i could lol and has also taught me a bit about the genetics of it.

If GA is used for halfway through veg then it has positive effects like slightly higher growth rates (although they need time to recover from this before transition or they'll be some weak ass plants) and increased levels of THC and CBD.

The PDF misses out parts like GA can stop your plants from transitioning to flower and that plants build up a tolerance to it.
Im going to have a quick look to see if there are any journals or white papers that support what I've seen in real life, if i do ill edit this post with a link.

Re: dosage. The paper talks of 50 micromol and 100micromol dosages. The 100 coincides with what i found to have positive impacts. I may have missed it skimming that PDF but at dosages lower than the 100micromoles or too much higher than 100micromoles the GA has negative impacts.
100 micromoles is equal to 3.45g per 100 litres. I used 3.5g per 100 litres

Thank you sir. I'm sure you'll regret it in the future lol

btw, the cannabinoid profile (and terpene etc profile) is established in the genetics of the seed.

I've grown CBD strains and used Thin Layer Chromatography (TLC - which we can do at home [rollitup link]) at only 3 weeks old to detect which seedlings are CBD-only/CBD+THC/THC-only etc. [rollitup link]

In other words you can use TLC to detect these terpenes and flavanoids etc, and do so with 3-week-old seedlings, saving months because you don't need to flower them through to harvest to find a good chemical profile.

Though, obviously youd need to use a different dye to the one we use for cannabinoids (Fast Blue B/BB), but I haven't looked into that.
It would also be slightly trickier to visualise because (individual) terpenes rarely reach above 5%, but, TLC is extremely sensitive :)

An area worth investigating.

ps. Fast Blue B/BB is also used to test for phenolics in other fruit such as strawberries.[sciencedirect link]

@DonTesla been using that insect frass as folair, seems to be working wonders. I was going to start doing some OMRI listed micro nutes (mostly for the boron and manganese), as folair too, do you think it would be dumb to mix \ do it the same evening? Or should I do them as separate feedings?
