Semi eater culture and keiki problems

Recently one of my orchids grew a keiki and i think it was brcause of stres and it wasn't really thriving before so after I cut the keiki i put it in water to try semi waterculture (4 days in eater 3 days dry) Now i have 2 problems 1. The keiki has 2 rots so i put one in the medium and one outside and watered it the same day its been 6 days the roots are green but the leaves are limp and idk why 2. The mother orchids leaves are also guite limp and a lot of the rots look like they're dying of is this normal in the trasition and what should I do - 1/3 of the roots was in water
