When to start feeding?

Hi all,

Not very experienced with growing chilis or any plants for that matter, but I love me some hot chilis which I cannot really find here in Switzerland. Here’s my first sprout, a capsicum chinense (Madame Jeanette). Immediately put it near the window, the apartment is very light and there’s plenty of sun throughout the day.

Due to issues I had in the previous – very dark – apartment and using potting soil (5 years ago, had so many bugs in there, thereafter I just gave up), I decided to use a coco/perlite mix this time. Now I’m wondering if it’s best to start with fertilizer right away, or only when the true leaves start appearing. I’ve read some mixed opinions on this.

Also, when repotting would it be ok to just keep using coco/perlite mix as a medium throughout the lifecycle? And just watering with added fertilizer.

Thanks 🙏🏼
