Soil is probably a little nutrient rich for small seedlings. Once they develop a larger root system, they’ll probably grow normally. @Wildflower This happens more often than you’d think. The other issue could be the ph is a little off. 6.0-6.8 is ideal in soil. Happy growing.
Thanks! I did accidentally get a soil that’s for transplanting so it’s got a kick to it and constant moisture battle right now but everything is still growing so that’s good haha.
