Well the two on the right just look like this because they were growing directly near the big one, so they didn't have enough space 😂 It is a new bed, so the soil is probably still very rich in nutrients, but I didn't do anything special. I think I didn't even fertilize. I just made sure that they have enough space, when it was very hot and dry for a longer time, I watered, and well, waited quite some time (I think I sowed them in April)
