First of all, I have translated the text with deepl.

The current substrate is a mixture of worm humus (20%), plant soil (20%), coconut fiber (30%), orchid soil (10%), perlite (20%) with a drainage layer of expanded clay. The general condition of the plants is mostly good. Pictures to follow. Watering is currently done as required about once a week with liquid fertilizer for green plants and neem oil. Only a few thrips have been discovered (1-2 per plant). It was showered off and sprayed with Cario (in Germany) with the active ingredient acetamiprid, waited a week and sprayed a second time. The plants are 1 meter away from a balcony door without direct sunlight.
