Turns out I mixed up the STS wrong you can't add part a and part B together incorrectly or it will precipitate and you will see brown in your mix it should be totally clear when you mix up STS or you have to do it again. Also don't use metal to stir it. Mixed up fresh worked amazing. I think it took three sprays total and I didn't have to spray right as I flipped it, you can spray it later. I think mine work 2 weeks in when they actually got the real stuff, The bottom half of those plants are still normal buds and they are pollinated by the top of the plant dropping feminized pollen to create feminized seeds.
