Unknown Plant Issues PLEASE HELP A ROOKIE GROWER!

Good morning my friends! I hope someone out there can help me. This is my 1st season growing outside and I've run into some issues. I have 5 plants. I started germination on April 19th and put them into solo cups on the 22nd. On May 6th I transplanted them into my garden. I've used fox farm soil for my grow.
Since they have been in my garden there have been little holes in my plants leaves. At first I thought they were bugs but as I did more research I started wondering if it was a nutrient problem. I went out and bought a all natural pesticide but that doesnt seem.to do anything. Anyways I hope to learn from some of the more knowledgeable people on this site and am completely open to suggestions, tips, and really anything that will help me be a better grower. I've attached some photo's. Looking forward to the advice!

That dirt under and around your plant does not look like fox farm.

before I planted them in the ground I dug it out. On the top it's all the shity soil but about 1inch down there is the foxfarm

Any ideas? Bugs or lack of nutrients?

It is caused by a very hungry caterpillar in my opinion. Those holes are damage from an insect with chewing mouthparts. Too irregular to be flea beetle. No shiny tracks from snails. Im going to stay with caterpillar...

Thats exactly what the dude at grow store said. I got myself a organic pesticide. Applied it last night and they Haven't gone near them again
