I brought my plants inside after trying an outdoor grow and the temps started dropping to the 40’s at night. All 3 were in flowering stage. Today I went to water and saw thrips on them. I did spray them with Deadbug - which I have never used on a flowering plant. Is it going to be ok? And How do you do a bud wash?
Captain Jacks Dead Bug? You can use CJDB in flower. For the bud wash, here ya go. Welcome aboard!!!
Welcome to the neighborhood. I hope you are able to get a handle on the insect situation.
