Ok so I've stumbled across this different recipe for STS treatment:
https://www.sigmaaldrich.com/technical-documents/protocols/biology/silver-thiosulfate.html
Someone at Strainhunters forum posted it with added quantities for the pentahydrate version of sodium thiosulfate.

Now, I have bought the salt from a private person and it had no label on it. Is there a way to check whether I have the pure or the pentahydrate version?
I have read the pentahydrate is the one they use as fixing salt, so chances are that I got this one. It worked for one experiment in the past but later on with different plants they didn't transform completely. I may have to buy a labelled product but wanted to know if I could use what I have before getting rid of it.
The person on Strainhunters is giving no word about the frequency or timing of application but states that it can be diluted for a working solution. Some other guy at instagram says he uses it undiluted but giving advice to use it only 2 times, once 2 weeks before 12:12 and again 2 weeks after 12:12.
Is someone else here using this main recipe with success and can talk about timing and dosage?
