Top dress with neem cake. Mix neem oil with a few drops of liquid soap and if possible, mix a little ginger, garlic, chilli extract. Spray on leaves and soil whichever is applicable. I do this in veg and no pests till harvest. If you can get your hands on some wood vinegar, that helps a lot too. Just add a bit to the watering each time. Keeps bugs away. You will get it after you smell it. Not foul at all, just smells smoky. I'm guessing thats what keeps pests away. Also has many other benefits you can Google.
