The holes in the leaves looks like they are from  snails or a caterpillar of some type. Try going out at night with a flashlight and picking off the guilty  subject. You can also poke around the soil to see if you find the enemy. Aphid do not do this type of damage. Another idea is to set a trap by laying a bit of damp rolled up newspaper near the plant. Slugs and snails will crawl into this at night and you can dispose of them. Keep growing, Marianne Binetti
