Prep for outdoors

Noticed some pre-flowering starting this week on all 3 strains. Largest is around 6 feet tall 5 feet diameter. Smallest is 5 feet tall 4 feet diameter. The Godfather strain seems to be getting attacked hard this week by cucumber beetles? I added a picture of the bug I keep seeing. I'm open to suggestions, I have tried neem oil and DE powder with no luck. It has rained alot this week so i havent added much nutrients they are water logged. But some of the bottom branches areshowing signs of yellowing leaves defoliating as needed. I mixed some heavy nutrients and added tonight right before another rain storm passes through. The one in full flower is blackjack it is indoors under 12/12.
