Nutrients Waira Talks to the Doc with Rx Blend....

@Waira @JohnEMad salicylic acid does initiate a SAR response but this does not directly help tric production and actually has a negative effect. Here is a reference article study in the arabidopsis test plant but the biosynthesis pathways are conserved across species so the results are relevant.

“The jar1-1 mutant exhibited normal trichome induction following treatment with jasmonic acid, suggesting that adenylation of jasmonic acid is not necessary. Salicylic acid had a negative effect on trichome production and consistently reduced the effect of jasmonic acid, suggesting negative cross-talk between the jasmonate and salicylate-dependent defense pathways. Interestingly, the effect of salicylic acid persisted in the nim1-1mutant, suggesting that the Npr1/Nim1 gene is not downstream of salicylic acid in the negative regulation of trichome production.”

Interactive Effects of Jasmonic Acid, Salicylic Acid, and Gibberellin on Induction of Trichomes in Arabidopsis - PMC

Leaf trichomes protect plants from attack by insect herbivores and are often induced following damage. Hormonal regulation of this plant induction response has not been previously studied. In a series of experiments, we addressed the effects of ...

Note that the jar1-1 mutant is lacking the signal pathway for JA which allows the study of this pathway in plants that would otherwise not respond normally to JA.

The most effective method of impacting the trichome/resin production pathways in trichome producing species of plants is through the jasmonic acid pathway. We have tackled this problem with our Precursor 1 nutrient. We don’t supply jasmonic acid (JA) directly, what we have done is to formulate Precursor 1 with components that have been shown in our experiments and in the scientific literature to support the plants natural biosynthesis mechanisms for JA and thereby allowing the plant to regulate its own metabolism but with the added support of making sure the specific resources are available to promote this mechanism. Like a gentle nudge saying we got your feed on point so go forth and make it sticky...

This is something we put a lot of time into and we definitely believe that Precursor 1 is better suited to increase tric development compared to many other products making that claim.

it does what?? ...Right then, full reverse on that misguided idea! Thanks Matt, I connected some errant dots then ...I trust in you!
Say, would a light foliar spraying of Precursor 1 tickle them in the right way? During bloom in particular..?
My feeds have been light, half at most, no more than 3x/week so far, and I'm just toasting the very tips on the more sensitive ones... Now comes the more challenging juggling act mate, as these cultivars start to separate out from each other in maturity... Likely I'll be making 2 different batches up for now and perhaps diluting where needed.
Update tomorrow - So far I'm more happy with this nute line than any other I have run to date! the tent is crowded, humid, some cool nights, a heat wave or two, and nobody shows any hiccups

@Waira unfortunately Precursor 1 won’t impact tric development as a foliar spray, it’s only effective when taken in through the roots. It doesn’t need to be at full strength though, the key is balance with the other nutrient components in solution. So it is still effective with the whole nutrient system at half strength.

Also, I should say that the SAR response has been shown to increase tric density in standalone experiments. The point I was trying to make is that when you look at the whole organism with complex crosstalk between metabolic pathways there is a negative feedback loop between Salicylic acid and Jasmonic Acid so you don’t want to stimulate both at the same time. Since Jasmonic acid has a stronger effect on tric density we found that was a better target to influence the final outcome. Plant physiology and metabolism is an evolving science and in the future we will know more and we won’t stop trying new things.

I am but a sponge Matt, soaking up every bit of this good stuff!

So, I jinxed myself apparently, today I saw some interveinal chlorosis starting up on a few girls,...consequences of the off-cue environmental factors as mentioned most likely,... RH% was just too high, lousy VPD...-- That should be fixed now! The photo girls are outta there, time to harden them off and get their light clocks set to actual local times... Also, it's so crowded that as anticipated, one of the Creepers is going full time OD's, the smaller one...
Meantime, they are stretching nicely, buds forming up well - ... some nice stank starting too

...forgot to add that the lot were foliar sprayed with Bio-Si, Kelpful, extra fulvic and micronutes which hopefully will see that halted... Damn I wish I had some Transport, gotta talk to Optic Foliar Dinesh!

They look perfect to me @Waira ! Gotta love that HubbaHaze girl.. bet she would beast given larger shoes and room to spread out, but LiversBx going to be a show stopper. Really nice structure.

@Waira I can’t find interveinal chlorosis in those photos... they look really good to me! You must be very tuned to the needs of your garden, or maybe you didn’t post the pic idk . Any plant would love that foliar treatment so they should show you some appreciation growth in the next few days.

I saw this pic but then realized it was just sunlight on a leaf... your garden is on point boss!

 

[Waira]

Thanks mates, appreciate the kind words! It shows better under the COB's, and it is pretty slight, but noticeable compared to 36h ago; it's mostly on Livers and OB... --for sure the flash covers it due to that mild gloss on leaf surfaces.
I hoping stretch slows down too, height may become an issue! I may have to rig the lights directly to the support bar to gain those extra inches... Next time I'm getting a taller tent, 5' isn't enough ...

 

[Waira]

<<<< Update >>>>

rolling along nicely so far,... There's some fan fade on Livers and OB... pH's all OK, upper 6's holding steady...
Big Data now going in at reduced dosage...
Somebody is kinda skunky, tent has a nice reek of it now!
