They were doing fine just a few days ago....I'm definitely a newbie to gardening. I know a thing or two but just the basics.
Could someone tell me what they see? Please I want them to grow up perfect.
Also, that soil looks very wet. You only need to water your plants when they need to be watered (top few inches are getting dry). Don't water then just for the sake of watering.
Over watering for sure. You need to move them to bigger pots at this point and put the 2 in 1 pot into separate pots. Get 3-5 gallon pots with good drainage and a soil mix with perlite.
In this case the choice of pot has helped insulate the roots from some of the heat.
Those ceramic garden pots have helped in this case. A plastic pot or grow bag would have cooked.
