It's overwatered see the big dark patch around the seedling? That seedling needs maybe a couple tablespoons of water and it looks like you have it a couple cups it's drowning from lack of oxygen. Give it way way way less water and start in a smaller container like a solo cup so at least if you over water it'll dry out faster. Number one killer of seedlings and young plants is over watering/ grower trying to do to much give let it grow or you'll baby it to death. It doesn't need watering everyday until it's huge I know you want to feel like you doing something but that'll kill it
Put a small stake in and tie her to it. Pointing her leaves upwards.
She's a little stretchy so next time don't add as much soil into the pot when you plant the seed. Wait for her to stretch a bit then just add extra soil around her stem when needed. This will help prop the seedling up and her stem under the soil will also start to sprout roots 👍😎🌱
hey there Diggie, i'm not a 100% sure about this one, but it looks like it could be linked to lack of humidity, as you know you should be above the 75% mark, if you're much below 55, it can lead to minor growth issues.... hope this helps ! 🚀
This happened to me once, can happen if you tray is not cleaned out properly, its a bacteria (cannot think of the name). My plant still grew fine but i had to build the soil up to support it for a couple days then it was fine
