Looking for a once and done pesticide that is safe and tests clean is flawed logic unless you can make some sort of valid argument that you have found a systemic pesticide that is safe to combust and inhale.
Diligence and patience is all it takes.
At a hobby scale getting brix right isn’t feasible. Soap and oil sprayed every 3 days on rotation is very feasible and will kill any foliar pest or fungi you encounter. I prefer JMS stylet oil because it actually does evaporate away in about 2 weeks. You could go with Suffoil-x early on, but as has been discussed here before, it does contain other unlabeled aromatic hydrocarbons of questionable safety. IME insecticidal soap is a commodity item, whatever is easy to get is fine, at hobby scale that is probably Safer brand.
Diligently rotate soap and oil, getting full coverage from spraying up twice a week and you’ll be good. Right now you’re likely moving plants to flower with pests on them. You have to eliminate them all before flower and then stop spraying around the 2nd or third week.
