I'm in Ft. Lauderdale Florida (10B). I have the same issue. I've got a plethora of differing varietals that I germinated outdoors in Solo cups beginning in March. Some plants are 6"-8" tall while others are just starting to sprout. My Thai Chili Peppers are growing exceptionally well while the bell peppers are taking there "sweet" time getting here. The struggle is real.

Do you use a plant heat mat. It can be bought online or may be found at garden centers like Lowes or Home Depot. Peppers like heat for good propagation

I'm actually in Thailand but your site doesn't list that. Having a hard time growing chilies here and looking for any hints. Soil has plenty of nutrients but does not dry out due to the rains and clay underlayer. At this point I'm thinking of adding sand to the soil to aid in drainage. I've dug a hole in the garden down to the clay layer and filled it with water. It drained within 5 minutes so it's really about my topsoil quality. Thanks!

Sand would be too heavy. You need to add compost or other organic matter into the soil when planting. To loosen soilup. Chilies/peppers do better in soil pH 6.5 to 7.0. Helpful info link https://bonnieplants.com/how-to-grow/growing-peppers/

Snails love small chilli plants so when you plant put some snail pallets around. Chilli doesn't grow well in small cup size plastic pots so don't use them or if you buy a chilli plant in one transplant to a large ceramic pot immediately. Grow from seed in a sandy garden bed seems to work very well to germinate, when the plants are as tall as your finger transplant them into a largish ceramic pot 2 litre minimum and don't be scared of leaving them in a large pot as they grow well in pots. Use a reasonable quality potting mix and water every day, mornings best, Full sun is best so find a spot where the chilli gets the maximum sun possible. The potting mix will have enough fertiliser for the next growth stage so don't add any fertiliser for the next month. Then add blood and bone and watch them grow quickly and start to flower. I've had really good results with blood and bone so have not needed to try alternative fertilisers like manure. The beauty of blood and bone is it is almost impossible to burn or kill your plants. Finally add potash fertiliser a month after the blood and bone to ensure the chilli bush has plenty of fruit. The chilli's ive grown in big pots grow jjust as good as the ones in the garden beds if not better. L put that down to the warm soil and potting mix. I live in Perth too so I hope you have luck with your chilli's
