At the beginning of the second week it resumed its growth, (5cm) then during the week I noted a lack of sulfur (by the slight discoloration of the leaves and the stems which turn purple) I added an additive in sulfur to fill is missing. Now she is 9cm at the end of her second week.
I noticed that the little one looking slightly for the light from the neck I brought the lamp closer, the neck is much better, with the lamp I use, from the neck I brought it closer the plant feels much better.
