Silver thiosulfate coco autoflower

Having a problem finding info on silver thiosulfate on autoflower for feminized seed production. As of lately my colloidal silver isn’t creating male flowers on my newer strains I am trying to grow in an ebb and flow coco coir setup .STS seems to be my next step. How often do you spray an autoflower ? Photo period plants you apparently spray once a week. If anyone has another alternative I am all ears. I am also going to try tiresias mist. My ph is between 5.7 and 6.2. Thank you for your consideration .
