Basically, I went to start my tomato seeds and realized all I had was some old potting mix. So I used that and planted the seeds on the bottom row. I ran out so I ended up going back to the store and getting seed starting mix to plant the ones in the top row. As you can see, the ones on the top are VASTLY outperforming the ones in potting mix. These are 2.5 weeks old and the ones in potting mix don't even have their true leaves. It's like they sprouted and have been stagnant since. The only difference is the soil. How do I help the bottom ones? Is the soil not as nutritious? Too dense? The bottom ones were the ones I was most excited about (hence why I planted them first), so I'd like to help them out.

Wow! What a difference.
Potting soil is normally just too dense for the little seedling roots to develop.
Additionally, the NPK levels are sometimes too high for seedling tomatoes.
It also isn’t always sterile.
Can you take a spoon and gently scoop out the seedlings and place them onto starting mix?
Were the two products from the same company?
I’ve taken potting mix and just sifted it to get Seedling Mix 🙂
What are the brands and exact product you used for each?
