@AllexStoriesStories, I did the same before but on my pepper plants. I grew them in soil and that was ok for them. But after I mixed some coco and perlite the are growing insanely. Pure soil is very compact and new seedlings don't have strong roots to break through the soil. It slows them down.
What you can do in future is grow your seedlings in smaller pots but in pots mix up some soil mixture I recommended. And never firmly pack your soil in pots, always break up your soil with hands so you don't have any clumps. If you don't have coco, you can mix up just with perlite or just coco and soil, and don't use 50/50 soil coco as you'd need to water your plants more frequently as you lose water retention with lots of coco.
My 14l pots with 60/40 mixture I mentioned can't retain more than 1.2l of water. Anything more just goes out of pot. Which sucks. No I know better 😀
My advice is to make your own soil. Get what ever you like or you can buy, grab a testing pot up to 4l and play with soil mixtures.
Just don't waste money on some expensive soils mixes. Good potting mix with pH of 6 to 6.8 is ok.
I like to make my own stuff that way I know how to handle it. But that's just me. 😋
