1st grow true noob

Everything's looking great so far👍. As for the white flies, they're pretty common. Can't tell you where they came from but they love hot, humid conditions. Couple tips (pending on your current environment)Removing any standing water, dropping temps to 21-24 celsius and lowering humidity should mitigate the spread. Also, sanitation/sterilization of surfaces would be good idea👍 . Diluted 3%H2o2 as a cleaning agent for surfaces (not plant!) works quite well. A good dry out of the soil, lower temps, lower humidity and an unwelcoming environment should eventually dry them up/kill them off. Removing affected leaves may also be a good course of action on near future. If it gets further out of hand, an organic insecticidal spray or neem oil concoction should do the trick. Good luck and happy grows!👌
