Basil

Basil is a fast-growing plant that can quickly overshadow its neighbors. Don't hesitate to prune it regularly to prevent it hindering the growth of its slower friends.

Have you pruned it properly? Basil hates having its leaves torn off one by one, leaving its stems bare. To get it right, refer to the video on your growth diary. Otherwise, it's normal for it to die after 4-5 months, as it's an annual plant.

Look closely at the stains: if they move, they're probably small bugs that you can scare away with a little black soap; if they don't move, it's likely that you've burnt your leaves by placing the fixture too close to them.
