Good luck on your reversal!
See if you can find a small box to put that bottle of STS into to keep it in complete darkness. Never used the STS as I've had only good luck with the colloidal silver. So no sense fixing it if it ain't broke. I hope they both work for you.
Don't know if I mentioned it here or not but I just started treating a Purple Punch plant two days ago. I trying to go from clone form to seed form with my favorite strains. So I'm reversing a few plants this summer and fall.
When it comes to reversing autos I would rather be early then late starting the application of (in my case) colloidal silver. I pretty much start applying the CS on about day 25 or 26 hoping the plant will start to show flowers by day 30. But if it takes till day 40 that's okay in my book. The first time I reversed the Quarter Pounder auto it took 39 days till I saw the first sign of pistils starting. The second one started on day 33 and they were both from the same pack of seeds. So that just shows that it's not cut and dry, there will be variations.
This photo is of the very first bud I've pollinated on my highly prized Gorilla Glue #4 plant. I'm gonna go out on a limb and say it's pollinated. Now I just have to wait to see if seeds form proving the pollen is viable.
