Next, I removed the lower two leaves because they were pushing the shoots above them upward. In the following days, the leaf tips started to curl slightly, so I adjusted the distance to the lamp. It is now hanging about 40 cm above the highest leaf, roughly 10 cm higher than before. Additionally, I continued to secure all the shoots as parallel to the ground as possible.
I've also started trimming back the clover. From now on, I add Bio Tabs Orgatrex to the watering water according to the instructions. By the end of the week, I notice that the leaves are developing a strange pattern. Additionally, I discover two or three small black spots on the leaves, which turn out to be thrips.
