Chitosan Oligosaccharide dosage?

@Rurumo so to summarize:

Chitosan is used as either a foliar or soil drench from early veg until harvest (at a dose of 200ppm to 500ppm)
Aspirin water is used later in veg to early flower (what dosage?)
Triacontanol you use alfa alfa meal, i know it can be used as either foliar or soil drench commonly this is used from early veg until harvest as well. I believe dosage should be between 25ppm to 100ppm and varies depending on whether it is a foliar feed or soil drench.

I’ve been playing with water soluble Triacontanol off of Alibaba.
$25 USD for a kilo of TC 1.5%EP. shipping costs more than the TC.
They suggested a gram per gallon. I use 20% of this.
Playing with application timing still.

Triacontanol is best used as a foliar spray but not in such high concentrations. I never go higher than 1 ppm. Most papers recommend 0,01-0,1 ppm to have the best effect for several species (there's no research for cannabis but some other species) and almost all apply it as a foliar spray. Everytime i sprayed with concentrations above 1 ppm some strains developed strange growth. There came 3 shoots out of some nodes instead of 2 (mainly seen on mother plants) and such things. It had no adverse effect though and after a few weeks the growth pattern normalized. I spray every 1-2 weeks until week 3.

1,5 % and water soluble? That sounds strange. Is there information about what else is in there? Or is that already a stock solution? Normally it is sold in concentrations of >90 % (5g of it last an eternity) and is per se not water soluble. You have to use polysorbate 20 (also called tween 20, a nonionic surfactant that is also a very good and cheap wetting agent btw) for it to dissolve in water for example (although there are some other ways like using methanol as a solvent iirc). Since it is used in tiny concentrations it is also best to make a stock solution of maybe 100 ppm (that corresponds to roughly 0,11g TRIA 90% per liter) and then use 10mL of that per liter to get a 1 ppm foliar spray. Instructions for preparation using Tween 20 can be found on YouTube.

Not sure but I bought a kg and was told one gram per gallon. Basically the gram you put in has 15mg of Tria. It’s pretty much a stock solution already in powdered form. Water soluble and have used through a full run now quite successfully... although at a much lower dosage than 1 gram a gallon.

Ok, if it works then everything is fine.
Do you use it in fertigation or as a foliar? And have you measured EC and/or Ph after addition? Just curious because if the main ingredient is some kind of filler/filling salt it should raise the EC quite a bit and could possibly throw your ratios off or even be detrimental if consisting of sodium salts etc. The filler sure could also be anything inert or a surfactant etc, just curious...

Sorry for the late response. I'm not on here as much as I used to be.

I definitely does raise EC, although I haven't noticed any ill effects. I've used it now on two full runs. Results were amazing.
It would mostly be filler, of which I'm not sure. The highest dose I've went was about 1/2 gram per gallon. That bumped me up about 100 ppm. I go easy on my EC.. pretty much 1.2 straight through flower... coco dtw... so the extra 100 isn't hurting anything.

1kg bag last a long long time. $23 USD for the bag.. like $50+ for the shipping.

I really like Advanced Nutrients Bud Explosion and Bud Factor X. Let's face it, they work well.. but expensive for easy to source ingredients.

I buy all my nutrients in 25lb bags.. Jacks 3-2-1. Won't pay for liquid.

Bud Explosion - Kelp and Tria
Bud Factor X - Chitosan, Salysilic Acid (and maybe Jasmonic Acid and a couple other things I'm also sourcing at the moment too thats in it)

I scored multiple KG's of both off Alibaba. Chitosan really brings out the frost, but if you hit it too early bud size and density will suffer alot.

I use chitosan in the last couple weeks only. I use tria throughout in varying amounts, and drop it the last two weeks.

I've found running Tria too late delays maturity and maybe causes foxtailing... foxtailing could have been me on that grow or stain specific.

My 2 cents.
