Hey,
For the bugs, you can get something like Buckley.. it's a food-safe insecticide and works pretty well, even for other pests.
It would be good to see a photo from above because it looks quite crowded; if that's the case, I recommend removing the large leaves from the bottom and middle, just about 20% so you'll improve air circulation. Better breathing, fewer bugs, more and better growth.
Good luck!
Happy growing! 👍
