My mornong glory’s leaves on my balcony has some problems. I’m not sure what could be the issue, some other plants show similar symthoms (celery’s leaves for example)

Can I ask for help from someone more experienced? I don’t know what I’m doing wrong.

I live in central EU, my balcony can get really hot, like 30-35 celsius. It gets direct sunlight from around 1-2 afternoon to 6-7. I water my plants daily, because of the heat, the soil dires quickly

      The little black specks look like thrip poop.

      Best chance to get rid of them is probably to smother them in some way. Neem oil or liquid soap mixed in water and sprayed on the plant, or sprinkling the plant and soil with diatomaceous earth are probably what I would try first.

      For the neem oil or liquid soap, it’s usually something between 2-5 mL (0.5-1 teaspoon) mixed in 1 L water.
