Over and under watering kind of mimic each other.
Most bagged soils have fertilizer in them, so you don't need to fertilizer for several weeks.
If your bed is elevated, above ground, I hope it can drain well.
Dig down in soil, if soppy wet, that's not good. You might want to get you a moisture meter, there like five bucks. Or use a wood bbq skewer, or chop stick, to check how deep soil is wet.
You want top inch or two of soil to dry before watering.
If soil down deep is wet. Just water shallow, when top couple inches are dry.
You'll get the hang of it. 😀👍👍
Pepper leafs will probably start straighting out. Of course, mine sometimes do that. The heat, cold nites, over/under watering, or over fertilization are the major causes, usually.
Let me know what ya find out.
Ttfn. New gardening friend. 😀👍👍
