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...
