Hello 👏
First of all, I recommend checking water Ph, probably there is some displacement. If you have land = make Ph 7-8.
And the second - the plant lacks a good climate around.
Take a plastic container from under meals, transparent, make holes in it, put a container on top of the plant.
And drink there from the pulvizer/ spray just water = to maintain high humidity.
In this way, I restored many plants at the first stages of growth.
With a container with holes from above - you need a few days to restore strength and strongly.
Water the plant very neatly, very in small volumes of water, and preferably around the plant so that the roots grow in width.
Water a small amount of water in 0.050 ml. 1 time in 2 -3 days. All the rest of the time - raise the installed cover - a container and puff 1 -2 - 3 times a day on the walls of this container - cover.
The container should be very transparent. With holes.
And within a few days, the plant should become stronger and begin recovery and healthy growth.
Good luck and good growth🙌
