I would suggest that you start over and do the proper research. I am very hasty as well when it comes to planting. I recently planted a decent sized container garden using potting mix, which dries up too quickly in which I have to water everyday. Potting mix really has no nutrients for plants, unless it is Miracle Gro which will feed your plants for a few months, but still it dries out too quickly. What I did was I went to Lowe's and bought Black Kow for $5.17, it's in a yellow bag. I used it as a top dressing on top of my potting mix. When it rains all the nutrients will drain down. Don't plant your garden in just compost without a mixture of different mediums. The soil needs to be airy, clay is a no go. Nothing grows well in clay. So my mixture is perlite - few small handfuls per container, which is about $4.00 for a small bag, potting mix - again about $5.00 a bag and then the Black Kow mixture.
You can also use mushroom compost - sold at Home Depot and Lowe's, or chicken manure. Every gardener has a differnet opinion and this is mine. Keep the Black Kow as a top dressing. Also invest in Alaska Fish Emulsion which is about $6.00 at Walmart. Use two capfuls per 1 gallon watering can and mix together well and water your plants. This is a great and cheap fertilizer!! Wait a few weeks and your plants will be thriving!! Use this fertilizer when seedlings have true leaves, when they set fruit and when the season changes.
Best of luck!!!!!
