Never use neem oil on budding flowers, It can ruin the taste and flavor. Never had spider mites so all I can say is what the internet tells me. dish soap( NOT detergent ) and water will control them. As for powdery mildew what I like to use is potassium bicarbonate. I have had the best results with it and have even gotten rid of it completely in some cases. Its completely safe for your plants and some people add it to their foliar feed spray as a preventative. Happy Growing

Mycos and Fans 😋 (The Fungi/bacteria kills the Eggs and is good for the Plant in many ways and the Fan is just so you get a nice circulation in the tent so the Dew cant form in the first place) Use Neem if you got the Pests already... my 2 Cents since you got some good answers already.

If you're not in flowering state (I forget to add it) you should spray the plants every 7 days with a combination of neem oil (or neem cake), potasium soap (15g*L) and cold water (at the temperature of your tap)
