Anyone to tell me what the plant has?

If the medium is dry water it, is the problem that its too wet for too long, roots not getting enough air, is it sat in tray of water? Adjust the mixture of your medium to match the need of your plants.

There is no such thing as too much water problem; only a medium with too much water retention for the environment it grows. Plastic pot, don't see any perlite either, no diary, no environmental metrics, no feeding history, I see coir in your soil too, that's another whole problem, was it buffered prior? PH reading, not "its fine", its clearly not. An ideal soil is commonly said to have 50% pore space (water + air), 5 % organic matter, and 45% minerals.

The same problem you had a week ago.
