The set of instructions I got said to do the first spray at 3 weeks into flower and that didn't work worth a crap. Since then I've gone with the first spray a few days before the flip then every 4 days until I see balls forming then quit. Other stuff says before flip then just 3 more 4 days apart then stop and balls will form in the next few days.
I'm sticking with the every 4 days until balls form method as that has worked fine the last 4 out of 7 times I've used STS. I basically have an unlimited supply of STS or at least enough to last my lifetime so don't much care if I'm using more than I need to as long as it gets the job done.
About giving too much STS do you mean too strong a mix or too many sprays? I went 50% higher after my first try then bumped it up to double the amount in each batch before seeing any leaf damage and it wasn't much compared to some of the pics I've seen of other's results while I was searching around for examples.
I think as long as you start around the flip it should work fine.
