If you over water them then yes, that does tend to happen, leave em a day or two days longer before you water them in the future, once a week should be enough at this stage as they have small root systems, and its not that warm out yet either. Let the soil dry out more before you water next. Its that or your PH is WAY off in the soil or your water. Id think its the over watering before the PH thou. The roots are likely not getting enough air to grow faster. So ease up on the watering til they are bigger ok?

Has hecho todo lo posible amigo Mi consejo: revisa la cinta en 5 días, es decir, quitala con cuidado y observa si ha cizatrizado Si el "nudo" está hecho, elimina la cinta. Si no, pon una cinta nueva y déjala 5 días más

The leaves position looks good, she seems to drink.. maybe she needs more air in the soil or more or less watering. But you saying "rich soil" makes me worry about the oxigen.. you can poke little holes in the soil, pretending you are a blackbird.😆
