5.4 The right placement of the silver thiosulfate
The precise placement or application location of silver thiosulfate (STS) in
Cannabis plants is crucial for effective absorption, assimilation, and sex reversal. Breeders suggest that the STS solution should be foliar sprayed onto the entire plant until runoff (
Lubell and Brand, 2018;
DiMatteo et al., 2020). Moreover,
Flajšman et al. (2021) indicated that the efficacy of STS application is higher when the entire plant is foliar sprayed, rather than specifically applying STS to the shoot tips. These studies confirm the efficiency of foliar application of STS as the most reliable application method, offering promise to
Cannabis cultivators for commercial application.
5.5 The right application frequency of silver thiosulfate
The frequency of STS application does not significantly affect the degree of masculinization in
Cannabis plants. Studies have shown that whether STS is applied to plants in three consecutive intervals of 7 days under vegetative stage (
Lubell and Brand, 2018) or with a single application followed by flower induction, all plants underwent masculinization in the same growth stage (
Flajšman et al., 2021). To minimize operational costs, a single application of STS is sufficient to induce maleness in female
Cannabis plants.
Following STS application, it is recommended to allow the plants to remain in a long photoperiod for up to 7 days before subjecting them to a short photoperiod to induce flowering. This delay is crucial to ensure proper assimilation of STS by the plant.

Interesting scientific article concludes that:
# One STS application is all that's really needed to reverse a cannabis plant. It does not need 3 x STS applications, as 3 applications does not significantly alter results.
# The *entire* plant/leaves should be sprayed until runoff, not just the nodes, and
# Best efficacy of the 1 application of STS is done at 7 days prior to flip to 12/12.
Other parts of the article( not included here)discusses the strength of STS application, and concludes that the STS should NOT be further diluted with water. Best results were observed at full strength STS application.
So, in summary. Spray the shit out of your entire plant( until runoff)at full strength STS, 7 days before flip to 12/12. No need to spray a second or third time.
Reminder, not all strains can be reversed. It's generally accepted that around 60% to 80% of strains can be reversed. I'm assuming(?) these same principles equally apply to autos and photos, as no distinction has been made on any study I have found, between autos and photos.
