First Indoor Autoflower Grow

Day 27 from seed. No signs of preflower. 2 of the healthier plants were topped and 3 let to grow natural I am anxious to see which yields more in this setup. Any addvice is appreaciated. I think I may have discovered a bug problem this week maybe mites or thripes so I sprayed the whole grow with neem oil and captain jacks deadbug spray. Also installed sticky pads and fly stripes trying to stay ahead of the problem before its a real issue. Thanks for looking. Ill update again next week.
